# HTTP Status Codes
## Categories
- **1XX** status codes: Informational Requests
- **2XX** status codes: Successful Requests
- **3XX** status codes: Redirects
- **4XX** status codes: Client Errors
- **5XX** status codes: Server Errors
## Complete List
| Code | Name | Description |
| ---- | ---------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| 100 | Continue | Everything so far is OK and that the client should continue with the request or ignore it if it is already finished. |
| 101 | Switching Protocols | The client has asked the server to change protocols and the server has agreed to do so. |
| 102 | Processing | The server has received and is processing the request, but that it does not have a final response yet. |
| 103 | Early Hints | Used to return some response headers before final HTTP message. |
| 200 | OK | Successful request. |
| 201 | Created | The server acknowledged the created resource. |
| 202 | Accepted | The client's request has been received but the server is still processing it. |
| 203 | Non-Authoritative Information | The response that the server sent to the client is not the same as it was when the server sent it. |
| 204 | No Content | There is no content to send for this request |
| 205 | Reset Content | Tells the user agent to reset the document which sent this request. |
| 206 | Partial Content | This response code is used when the range-header is sent from the client to request only part of a resource. |
| 207 | Multi-Status | Conveys information about multiple resources, for situations where multiple status codes might be appropriate. |
| 208 | Already Reported | The members of a DAV binding have already been enumerated in a preceding part of the multi-status response. |
| 226 | IM Used | IM is a specific extension of the HTTP protocol. The extension allows a HTTP server to send diffs (changes) of resources to clients. |
| 300 | Multiple Choices | The request has more than one possible response. The user agent should choose one. |
| 301 | Moved Permanently | The URL of the requested resource has been changed permanently. The new URL is given in the response. |
| 302 | Found | This response code means that the URI of requested resource has been changed temporarily |
| 303 | See Other | The server sent this response to direct the client to get the requested resource at another URI with a GET request. |
| 304 | Not Modified | It tells the client that the response has not been modified, so the client can continue to use the same cached version of the response. |
| 305 | Use Proxy | Defined in a previous version of the HTTP specification to indicate that a requested response must be accessed by a proxy. (discontinued) |
| 307 | Temporary Redirect | The server sends this response to direct the client to get the requested resource at another URI with same method that was used in the prior request. |
| 308 | Permanent Redirect | This means that the resource is now permanently located at another URI, specified by the Location: HTTP Response header. |
| 400 | Bad Request | The server could not understand the request |
| 401 | Unauthorized | The client didn't authenticate himself. |
| 402 | Payment Required | This response code is reserved for future use. The initial aim for creating this code was using it for digital payment systems, however this status code is used very rarely and no standard convention exists. |
| 403 | Forbidden | The client does not have access rights to the content |
| 404 | Not Found | The server can not find the requested resource |
| 405 | Method Not Allowed | The request method is known by the server but is not supported by the target resource |
| 406 | Not Acceptable | The reponse doens't conforms to the creteria given by the client |
| 407 | Proxy Authentication Required | This is similar to 401 Unauthorized but authentication is needed to be done by a proxy. |
| 408 | Request Timeout | This response is sent on an idle connection by some servers, even without any previous request by the client. |
| 409 | Conflict | This response is sent when a request conflicts with the current state of the server. |
| 410 | Gone | This response is sent when the requested content has been permanently deleted from server, with no forwarding address. |
| 411 | Length Required | Server rejected the request because the Content-Length header field is not defined and the server requires it. |
| 412 | Precondition Failed | Access to the target resource has been denied. |
| 413 | Payload Too Large | Request entity is larger than limits defined by server. |
| 414 | Request-URI Too Long | The URI requested by the client is longer than the server is willing to interpret. |
| 415 | Unsupported Media Type | The media format is not supported by the server. |
| 416 | Requested Range Not Satisfiable | The range specified by the Range header field in the request cannot be fulfilled. |
| 417 | Expectation Failed | the expectation indicated by the Expect request header field cannot be met by the server. |
| 418 | I'm a teapot | The server refuses the attempt to brew coffee with a teapot. |
| 421 | Misdirected Request | The request was directed at a server that is not able to produce a response. |
| 422 | Unprocessable Entity | The request was well-formed but was unable to be followed due to semantic errors. |
| 423 | Locked | The resource that is being accessed is locked. |
| 424 | Failed Dependency | The request failed due to failure of a previous request. |
| 426 | Upgrade Required | The server refuses to perform the request using the current protocol but might be willing to do so after the client upgrades to a different protocol. |
| 428 | Precondition Required | his response is intended to prevent the 'lost update' problem, where a client GETs a resource's state, modifies it and PUTs it back to the server, when meanwhile a third party has modified the state on the server, leading to a conflict. |
| 429 | Too Many Requests | The user has sent too many requests in a given amount of time |
| 431 | Request Header Fields Too Large | The server is can't process the request because its header fields are too large. |
| 444 | Connection Closed Without Response | The connection opened, but no data was written. |
| 451 | Unavailable For Legal Reasons | The user agent requested a resource that cannot legally be provided (such as a web page censored by a government) |
| 499 | Client Closed Request | The client closed the connection, despite the server was processing the request already. |
| 500 | Internal Server Error | The server has encountered a situation it does not know how to handle. |
| 501 | Not Implemented | The request method is not supported by the server and cannot be handled. |
| 502 | Bad Gateway | This error response means that the server, while working as a gateway to get a response needed to handle the request, got an invalid response. |
| 503 | Service Unavailable | The server is not ready to handle the request. |
| 504 | Gateway Timeout | This error response is given when the server is acting as a gateway and cannot get a response in time. |
| 505 | HTTP Version Not Supported | The HTTP version used in the request is not supported by the server. |
| 506 | Variant Also Negotiates | the chosen variant resource is configured to engage in transparent content negotiation itself, and is therefore not a proper end point in the negotiation process. |
| 507 | Insufficient Storage | The method could not be performed on the resource because the server is unable to store the representation needed to successfully complete the request. |
| 508 | Loop Detected | The server detected an infinite loop while processing the request. |
| 510 | Not Extended | Further extensions to the request are required for the server to fulfill it. |
| 511 | Network Authentication Required | Indicates that the client needs to authenticate to gain network access. |
| 599 | Network Connect Timeout Error | The connection timed out due to a overloaded server, a hardware error or a infrastructure error. |

# Markdown
Markdown is a text-to-HTML conversion tool for web writers. Markdown allows you to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid XHTML (or HTML).
Documentation: [Markdown Docs](https://daringfireball.net/projects/markdown/)
RFC: [RFC 7763](https://www.rfc-editor.org/rfc/rfc7763)
GitHub Documentation: [Writing Markdown on GitHub](https://docs.github.com/en/get-started/writing-on-github)

## Cheat-Sheet
### Headings
```markdown
# Heading 1
## Heading 2
### Heading 3
#### Heading 4
##### Heading 5
###### Heading 6
```
Here is a heading: `# Heading`, **don't do this:** `#Heading`
### Emphasis
```markdown
Emphasis, aka italics, with *asterisks* or _underscores_.
Strong emphasis, aka bold, with **asterisks** or __underscores__.
Combined emphasis with **asterisks and _underscores_**.
Strikethrough uses two tildes. ~~Scratch this.~~
```
### Line Breaks
```markdown
First line with two spaces after.
And the next line.
```
### Lists
#### Ordered Lists
```markdown
1. First item
2. Second item
3. Third item
```
#### Unordered Lists
```markdown
- First item
- Second item
- Third item
```
### Links
```markdown
Link with text: [link-text](https://www.google.com)
```
### Images
```markdown
Image with alt text: ![alt-text](https://camo.githubusercontent.com/4d89cd791580bfb19080f8b0844ba7e1235aa4becc3f43dfd708a769e257d8de/68747470733a2f2f636e642d70726f642d312e73332e75732d776573742d3030342e6261636b626c617a6562322e636f6d2f6e65772d62616e6e6572342d7363616c65642d666f722d6769746875622e6a7067)
Image without alt text: ![](https://camo.githubusercontent.com/4d89cd791580bfb19080f8b0844ba7e1235aa4becc3f43dfd708a769e257d8de/68747470733a2f2f636e642d70726f642d312e73332e75732d776573742d3030342e6261636b626c617a6562322e636f6d2f6e65772d62616e6e6572342d7363616c65642d666f722d6769746875622e6a7067)
```
### Code Blocks
#### Inline Code Block
```markdown
Inline `code` has `back-ticks around` it.
```
#### Blocks of Code
<pre>
```javascript
var s = "JavaScript syntax highlighting";
alert(s);
```
```python
s = "Python syntax highlighting"
print s
```
```
No language indicated, so no syntax highlighting.
But let's throw in a <b>tag</b>.
```
</pre>
### Tables
There must be at least 3 dashes separating each header cell.
The outer pipes (|) are optional, and you don't need to make the raw Markdown line up prettily.
```markdown
| Heading 1 | Heading 2 | Heading 3 |
|---|---|---|
| col1 | col2 | col3 |
| col1 | col2 | col3 |
```
### Task list
To create a task list start line with square brackets with an empty space.
Ex: [ <space> ] and add text for task.
To check the task replace the space between the bracket with "x".
```markdown
[x] Write the post
[ ] Update the website
[ ] Contact the user
```

# SSL/TLS Certificates
X.509 is an ITU standard defining the format of public key certificates. X.509 are used in TLS/SSL, which is the basis for HTTPS. An X.509 certificate binds an identity to a public key using a digital signature. A certificate contains an identity (hostname, organization, etc.) and a public key (RSA, DSA, ECDSA, ed25519, etc.), and is either signed by a Certificate Authority or is Self-Signed.
## Self-Signed Certificates
### Generate CA
1. Generate RSA
```bash
openssl genrsa -aes256 -out ca-key.pem 4096
```
2. Generate a public CA Cert
```bash
openssl req -new -x509 -sha256 -days 365 -key ca-key.pem -out ca.pem
```
### Optional Stage: View Certificate's Content
```bash
openssl x509 -in ca.pem -text
openssl x509 -in ca.pem -purpose -noout -text
```
### Generate Certificate
1. Create a RSA key
```bash
openssl genrsa -out cert-key.pem 4096
```
2. Create a Certificate Signing Request (CSR)
```bash
openssl req -new -sha256 -subj "/CN=yourcn" -key cert-key.pem -out cert.csr
```
3. Create a `extfile` with all the alternative names
```bash
echo "subjectAltName=DNS:your-dns.record,IP:257.10.10.1" >> extfile.cnf
```
```bash
# optional
echo extendedKeyUsage = serverAuth >> extfile.cnf
```
4. Create the certificate
```bash
openssl x509 -req -sha256 -days 365 -in cert.csr -CA ca.pem -CAkey ca-key.pem -out cert.pem -extfile extfile.cnf -CAcreateserial
```
## Certificate Formats
X.509 Certificates exist in Base64 Formats **PEM (.pem, .crt, .ca-bundle)**, **PKCS#7 (.p7b, p7s)** and Binary Formats **DER (.der, .cer)**, **PKCS#12 (.pfx, p12)**.
### Convert Certs
COMMAND | CONVERSION
---|---
`openssl x509 -outform der -in cert.pem -out cert.der` | PEM to DER
`openssl x509 -inform der -in cert.der -out cert.pem` | DER to PEM
`openssl pkcs12 -in cert.pfx -out cert.pem -nodes` | PFX to PEM
## Verify Certificates
`openssl verify -CAfile ca.pem -verbose cert.pem`
## Install the CA Cert as a trusted root CA
### On Debian & Derivatives
- Move the CA certificate (`ca.pem`) into `/usr/local/share/ca-certificates/ca.crt`.
- Update the Cert Store with:
```bash
sudo update-ca-certificates
```
Refer the documentation [here](https://wiki.debian.org/Self-Signed_Certificate) and [here.](https://manpages.debian.org/buster/ca-certificates/update-ca-certificates.8.en.html)
### On Fedora
- Move the CA certificate (`ca.pem`) to `/etc/pki/ca-trust/source/anchors/ca.pem` or `/usr/share/pki/ca-trust-source/anchors/ca.pem`
- Now run (with sudo if necessary):
```bash
update-ca-trust
```
Refer the documentation [here.](https://docs.fedoraproject.org/en-US/quick-docs/using-shared-system-certificates/)
### On Arch
System-wide – Arch(p11-kit)
(From arch wiki)
- Run (As root)
```bash
trust anchor --store myCA.crt
```
- The certificate will be written to /etc/ca-certificates/trust-source/myCA.p11-kit and the "legacy" directories automatically updated.
- If you get "no configured writable location" or a similar error, import the CA manually:
- Copy the certificate to the /etc/ca-certificates/trust-source/anchors directory.
- and then
```bash
update-ca-trust
```
wiki page [here](https://wiki.archlinux.org/title/User:Grawity/Adding_a_trusted_CA_certificate)
### On Windows
Assuming the path to your generated CA certificate as `C:\ca.pem`, run:
```powershell
Import-Certificate -FilePath "C:\ca.pem" -CertStoreLocation Cert:\LocalMachine\Root
```
- Set `-CertStoreLocation` to `Cert:\CurrentUser\Root` in case you want to trust certificates only for the logged in user.
OR
In Command Prompt, run:
```sh
certutil.exe -addstore root C:\ca.pem
```
- `certutil.exe` is a built-in tool (classic `System32` one) and adds a system-wide trust anchor.
### On Android
The exact steps vary device-to-device, but here is a generalised guide:
1. Open Phone Settings
2. Locate `Encryption and Credentials` section. It is generally found under `Settings > Security > Encryption and Credentials`
3. Choose `Install a certificate`
4. Choose `CA Certificate`
5. Locate the certificate file `ca.pem` on your SD Card/Internal Storage using the file manager.
6. Select to load it.
7. Done!

# Zero Trust
Zero Trust is a security concept and framework that assumes no level of trust by default for any user, device, or network component, regardless of whether they are inside or outside the organization's network perimeter. It emphasizes the need for strict access controls and authentication measures at all levels, such as verifying user identity, device security posture, and continuously monitoring user activities. Zero Trust aims to enhance overall security posture and protect against internal and external threats by minimizing potential attack surfaces and adopting a more granular and dynamic approach to security.
## Zero Trust Network Access (ZTNA)
Zero Trust Network Access (ZTNA) is a specific implementation of Zero Trust principles that focuses on providing secure access to internal resources and applications for authorized users, regardless of their location or the network they are connecting from.
