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. +.PP +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. +.SH SOURCE +.B /sys/src/libsec +.SH SEE ALSO +.IR mp (2), +.IR aes (2), +.IR des (2), +.IR dsa (2), +.IR elgamal (2), +.IR rc4 (2), +.IR rsa (2), +.IR sechash (2), +.IR prime (2), +.IR rand (2) -- cgit v1.2.3
