function Generate-JwtSecret {
|

<#
|
||
|
|
.SYNOPSIS
|
||
|
|
Generates a secure, Base64-encoded random string suitable for a JWT secret (HS256).
|
||
|
|
|
||
|
|
.DESCRIPTION
|
||
|
|
This function creates a cryptographically strong, random byte array of a specified length
|
||
|
|
(defaulting to 32 bytes/256 bits) and then encodes it to a Base64 string.
|
||
|
|
This is ideal for use as a symmetric key in JWTs (e.g., for HS256 algorithm).
|
||
|
|
|
||
|
|
.PARAMETER Length
|
||
|
|
Specifies the length of the random byte array in bytes.
|
||
|
|
A length of 32 bytes (256 bits) is generally recommended for HS256.
|
||
|
|
Defaults to 32 if not specified.
|
||
|
|
|
||
|
|
.EXAMPLE
|
||
|
|
Generate-JwtSecret
|
||
|
|
|
||
|
|
This will generate a 32-byte (256-bit) Base64-encoded JWT secret.
|
||
|
|
|
||
|
|
.EXAMPLE
|
||
|
|
Generate-JwtSecret -Length 64
|
||
|
|
|
||
|
|
This will generate a 64-byte (512-bit) Base64-encoded JWT secret.

function Copy-FileContent {
|
||
|
|
<#
|
||
|
|
.SYNOPSIS
|
||
|
|
Copies the content of a specified file to the clipboard.
|
||
|
|
|
||
|
|
.DESCRIPTION
|
||
|
|
The Copy-FileContent function reads the entire content of a specified text file
|
||
|
|
and places that content onto the system clipboard using Set-Clipboard.
|
||
|
|
This function can be invoked using its alias 'catc'.
|
||
|
|
|
||
|
|
The function is designed to be silent in terms of explicit success messages.
|
||
|
|
If an error occurs (e.g., file not found, permission issues, clipboard error),
|
||
|
|
it will throw a terminating error. This allows the calling script or user
|
||
|
|
to handle the error using standard PowerShell try/catch blocks or by checking
|
||
|
|
the $? automatic variable.
|
||
|
|
|
||
|
|
.PARAMETER Path
|
||
|
|
Specifies the path to the file whose content will be copied to the clipboard.
|
||
|
|
This parameter is mandatory. It accepts pipeline input.
|
||
|
|
|
||
|
|
.EXAMPLE
|
||
|
|
PS C:\> Copy-FileContent -Path "C:\Users\Me\Documents\MyNotes.txt"
|
||
|
|
# Copies the content of MyNotes.txt to the clipboard.
|
||
|
|
# If successful, $? will be $true. If an error occurs, it will be $false
|
||
|
|
# and an error record will be generated.
|
||
|
|
|
||
|
|
.EXAMPLE
|
||
|
|
PS C:\> catc "C:\Logs\important.log"
|
||
|
|
# Uses the alias 'catc' to copy the content of important.log to the clipboard.
|
||
|
|
|
||
|
|
.EXAMPLE
|
||
|
|
PS C:\> try {
|
||
|
|
PS C:\> catc "C:\path\to\nonexistentfile.txt"
|
||
|
|
PS C:\> Write-Host "File content copied successfully."
|
||
|
|
PS C:\> }
|
||
|
|
PS C:\> catch {
|
||
|
|
PS C:\> Write-Error "Operation failed: $($_.Exception.Message)"
|
||
|
|
PS C:\> # A calling script could use 'exit 1' here if needed
|
||
|
|
PS C:\> }
|
||
|
|
# This example shows how to catch and handle errors from the function.
|
||
|
|
|
||
|
|
.EXAMPLE
|
||
|
|
PS C:\> "C:\Temp\data.log" | catc
|
||
|
|
PS C:\> if ($?) {
|
||
|
|
PS C:\> # Optional: Perform action on success, though the function is silent.
|
||
|
|
PS C:\> } else {
|
||
|
|
PS C:\> Write-Warning "catc command failed for data.log."
|
||
|
|
PS C:\> }
|
||
|
|
# Checks the success status after execution.
|
||
|
|
|
||
|
|
.OUTPUTS
|
||
|
|
None. This function does not output any objects to the pipeline. It interacts
|
||
|
|
with the clipboard. On error, it writes an error record to the error stream.
