PowerShell String-hashing Function

Get-StringHash.ps1

# This is a customized version of the work done by jermity: https://gist.github.com/jermity/d38da10534a7a56af32d
# Examples:
#  To List all available algorithms:
#    Get-StringHash -List
#
#  To hash the string using all available algorithms:
#    'test' | Get-StringHash -All
#
#  To do the same as above, but without using the pipeline:
#     Get-StringHash -String 'test' -All
#
#  To hash the string using a specific algorithm:
#    'test' | Get-StringHash -HashName SHA1
#
#  To do the same as above, but without using the pipeline:
#    Get-StringHash -HashName SHA1 -String 'test'
