ConvertBase64

A pair of PowerShell cmdlets for converting to and from Base64 strings.

Usage

The commands are simple and intuitive to use:

Convert to Base64

The easiest way to convert to Base64 is to simply pipe a text string in to the command:

"Hello World!" | ConvertTo-Base64

That outputs the Base64 representation of the input test:

SGVsbG8gV29ybGQh

The byte encoding of the input text can be configured with the -Encoding parameter. The default encoding is UTF8.

The command can also be used to convert raw byte arrays to Base64 with:

ConvertTo-Base64 -Bytes @(0, 1, 2)

A convenient alias exists for the command:

"Hello World!" | ctb

Convert from Base64

The ConvertFrom-Base64 command works in a similar fashion, simply pipe a Base64 payload into it:

"SGVsbG8gV29ybGQh" | ConvertFrom-Base64

And it will output the decoded text:

Hello World!

This too features an -Encoding parameter for configuring the byte encoding when decoding the text output.

But it can also output raw byte arrays:

"AAEC" | ConvertFrom-Base64 -OutputBytes

Which will result in a byte array:

0
1
2

This too comes with a similarly named alias:

"SGVsbG8gV29ybGQh" | cfb
