CipherMode Parameter (Protect-Data Cmdlet)

The cipher mode of operation.


Protect-Data -CipherMode string


The cipher mode of operation. Possible values are:

CBC (default) The Cipher Block Chaining (CBC) is a mode of operation for a block cipher, one in which a sequence of bits is encrypted as a single unit or block with a cipher key applied to the entire block.
ECBThe Electronic Codebook (ECB) mode encrypts each block separately. Important: It is not recommend to use this model when encrypting more than one block because it may introduce security risks.
OFBThe Output Feedback (n-bit, NOFB) mode makes a block cipher into a synchronous stream cipher. It has some similarities to CFB mode in that it permits encryption of differing block sizes, but has the key difference that the output of the encryption block function is the feedback (instead of the ciphertext).
CFBThe Cipher Feedback (CFB) mode processes a small amount of incremental text into ciphertext, rather than processing a whole block at one time.
CTSThe Cipher Text Stealing (CTS) mode handles any length of plain text and produces cipher text whose length matches the plain text length. This mode behaves like the CBC mode for all but the last two blocks of the plain text.
8OFB8-bit Output Feedback (OFB) cipher mode.
