One-liners encoding and decoding Base64 in powershell

base64

[System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes("SecretMessage"))
[System.Text.Encoding]::UTF8.GetString([System.Convert]::FromBase64String("U2VjcmV0TWVzc2FnZQ=="))

Thanks! :)

BASE64 is NOT an encryption code. It is more kind of DEcompression.
By limitting the amount of usable characters to 64 characters (use only 6 bits instead of 8 bits).
You are now able to transform any binairy value into a readable Characterset.
You will need about 33% extra space. (any 6 bits binairy info will use 8 bits)
The length of "SecretMessage no way." is 21 characters and is transfored into "U2VjcmV0TWVzc2FnZSBubyB3YXku" which is 28 characters.
Every 4 characters in BASE64 will be transformed into 3 normal bytes.

@B-Art, context? I don't see anyone purporting base-64 encodement to be a method of encryption.

By the way, if any readers are interested in this, this SO answer explains well.
