Get-Hash
SYNOPSIS
PSCX Cmdlet: Gets the hash value for the specified file or byte array via the pipeline.
SYNTAX
Path (Default)
Get-Hash [-Algorithm <String>] [-Path] <PscxPathInfo[]> [<CommonParameters>]
Object
Get-Hash [-Algorithm <String>] [-StringEncoding <StringEncodingParameter>] -InputObject <PSObject>
[<CommonParameters>]
LiteralPath
Get-Hash [-Algorithm <String>] [-LiteralPath] <PscxPathInfo[]> [<CommonParameters>]
DESCRIPTION
Gets the hash value for the specified file or byte array via the pipeline. The default hash algorithm is MD5, although you can specify other algorithms using the -Algorithm parameter (MD5, SHA1, SHA256, SHA384, SHA512 and RIPEMD160). This cmdlet emits a HashInfo object that has properties for Path, Algorithm, HashString and Hash.
EXAMPLES
EXAMPLE 1
PS C:\>
C:\PS> Get-Hash $PSHOME\PowerShell.exe
Algorithm: MD5
Path : C:\Windows\System32\WindowsPowerShell\v1.0\PowerShell.exe
HashString : E22825B10BE3E8709BA1AB4D2DF36B57
Gets the MD5 hash (default hash algorithm) of the PowerShell executable.
EXAMPLE 2
PS C:\>
C:\PS> Get-Hash $PSHOME\PowerShell.exe -Algorithm SHA1
Algorithm: SHA1
Path : C:\Windows\System32\WindowsPowerShell\v1.0\PowerShell.exe
HashString : 3BA6DDF13A5DEDE95D427E7EFFEDFBC6F1BB267D
Gets the SHA1 hash of the PowerShell executable.
EXAMPLE 2
PS C:\>
C:\PS> "Hello" | Get-Hash -Algorithm SHA1 -StringEncoding Ascii
Algorithm: SHA1
Path :
HashString : F7FF9E8B7BB2E09B70935A5D785E0CC5D9D0ABF0
Gets the SHA1 hash of the string "Hello" interpreted as Ascii characters.
PARAMETERS
-LiteralPath
Specifies a path to the item. The value of -LiteralPath is used exactly as it is typed. No characters are interpreted as wildcards. If the path includes escape characters, enclose it in single quotation marks. Single quotation marks tell Windows PowerShell not to interpret any characters as escape sequences.
