Blowfish is Bruce Schneier’s symmetric block cipher. It supports
|
||
|
|
variable length keys from 32 to 448 bits and has a block size
|
||
|
|
of 64 bits. Both CBC and ECB modes are supported.

setupBFstate takes a BFstate structure, a key of at most 56 bytes,
|
||
|
|
the length of the key in bytes, and an initialization vector of
|
||
|
|
8 bytes (set to all zeroes if argument is nil). The encryption
|
||
|
|
and decryption functions take a BFstate structure, a data buffer,
|
||
|
|
and a length, which must be a multiple of eight bytes as padding
|
||
|
|
is
|
||
|
|
currently unsupported.<br>
