86 RSA BSAFE Crypto-C Library Reference Manual
Type of padding schemes available:Crypto-C procedures to use with algorithm object:
B_EncryptInit, B_EncryptUpdate, B_EncryptFinal, B_DecryptInit,
B_DecryptUpdate, and B_DecryptFinal. You may pass (B_ALGORITHM_OBJ)NULL_PTR
for all
randomAlgorithm
arguments.
Algorithm methods to include in application’s algorithm chooser:
the block cipher AM and the feedback mode AM specified by
encryptionMethodName
and
feedbackMethodName
, respectively.
Padding Scheme Reference String Comments
Standard CBC padding “pad”
No padding “nopad” Input length must be a multiple of cipher
block length (= 8 for all but rc5_64)
Stream “stream” Only available when using CFB in 1-bit and 8-
bit modes.
