Encoding/decoding between a URL and Base64 or do you mean things like InternetCanonicalizeUrl and UrlEscape – Juror

I meant encoding certain characters in a URL by replacing them with one or more character triplets that consist of the percent character "%" followed by two hexadecimal digits. – Rudderhead

PS C:\Temp>[System.Convert]::ToBase64String($b)
SGVsbG8gV29ybGQ=

PS C:\Temp>$b  = [System.Convert]::FromBase64String("SGVsbG8gV29ybGQ=")
PS C:\Temp>[System.Text.Encoding]::UTF8.GetString($b)

For URL encode/decode you could use:

[Reflection.Assembly]::LoadWithPartialName("System.Web") | Out-Null
[System.Web.HttpUtility]::UrlEncode("http://test.com/?path=what is")
http%3a%2f%2ftest.com%2f%3fpath%3dwhat+is
