		30	`.PP`
		31	`Blowfish is Bruce Schneier's symmetric block cipher. It supports`
		32	`variable length keys from 32 to 448 bits and has a block size of 64`
		33	`bits. Both CBC and ECB modes are supported.`
		34	`.PP`
		35	`setupBFstate takes a BFstate structure, a key of at most 56 bytes, the`
		36	`length of the key in bytes, and an initialization vector of 8 bytes`
		37	`(set to all zeroes if argument is nil). The encryption and decryption`
		38	`functions take a BFstate structure, a data buffer, and a length, which`
		39	`must be a multiple of eight bytes as padding is currently unsupported.`
