Key Length key:
Min = Minimum; Max = Maximum; Rec = Recommended; NR =No restrictions
The key lengths for the methods in the table below can be specified as absolute values. The valid key length is any value specified in either of the Key Length columns, but not the values between them.
No. of Key lengths: Specifies how many keys are supported .
Supported key lengths: Specifies the supported key lengths.

Note:
|
The Block cipher (including CBC) works on full blocks. If the last block is incomplete, it is padded with NULLs. Therefore, after deciphering, you should remove the padding. Alternatively, use the CFB or OFB stream ciphers.
