Unprotect-Data Cmdlet

Parameters   Output Objects   Configuration Settings  

The Unprotect-Data cmdlet supports decrypting data with various symmetric algorithms including AES, 3DES, and more.

Syntax

Unprotect-Data [parameters]

Remarks

The Unprotect-Data cmdlet provides a simple way to decrypt data or files. The following algorithms are supported:

• AES (default)
• Blowfish
• CAST
• DES
• IDEA
• RC2
• RC4
• TEA
• TripleDES
• Twofish
• Rijndael

To begin, specify the input data through either InputMessage or InputFile. If OutputFile is set the decrypted data will be written to the specified file, otherwise it will be returned in the OutputMessage object.

Next, set KeyPassword, and specify the Algorithm if required. Additional parameters that affect the algorithm include CipherMode and PaddingMode.

If the input is hex encoded set UseHex to hex decode the input before decrypting.

Additional options include specifying Key and InitializationVector instead of KeyPassword, decrypting block-by-block via InputBlockB, specifying KeySize, KeyPasswordAlgorithm, and more.

Encrypt Examples

#Encrypt a string with AES and default options
$encryptedData = Protect-Data -InputMessage test -KeyPassword password

#Encrypt a string to file with 3DES
Protect-Data -InputMessage test -KeyPassword password -OutputFile C:\encrypted.dat -Algorithm tripledes

#Encrypt a file to string and hex encode it
Protect-Data -InputFile C:\test.txt -KeyPassword password -UseHex

Decrypt Examples

#Decrypt a string with AES
Unprotect-Data -InputMessageB $encryptedData.DataB -KeyPassword password

#Decrypt a file to string with 3DES
Unprotect-Data -InputFile C:\encrypted.dat -KeyPassword password -Algorithm tripledes

#Decrypt a string to file and hex decode it
Unprotect-Data -InputMessage ADE51B29E36B2C1FCB4C9A1BEB8884AE -KeyPassword password -UseHex -OutputFile C:\test.decrypted.txt
