Documentation

Computes the Tiger cryptographic hash function at the 192 bit digest size.

See message-digest-primitive for more information.

Tiger API

Component export

Usage

(use tiger-hash-api)

Constants

name
algorithm name ; symbol
version
algorithm version ; string
context-size
context byte length ; fixnum
digest-length
final byte length ; fixnum
block-length
buffer byte length ; fixnum

Note that block-length is informational only.

init

init CTXprocedure

Initializes a 192-bit Tiger hash CTX, with at least context-size byte size.

update

update CTX OBJ LENprocedure

Accumulate LEN bytes from the Scheme OBJ into CTX.

raw-update

raw-update CTX PTR LENprocedure

Accumulate LEN bytes from the byte PTR into CTX.

final

final CTX OBJprocedure

Finalize the CTX into a Scheme OBJ with at least digest-length byte size. The target is usually a blob, u8vector, or string.

Tiger Primitive

Packaged export

Usage

(use tiger-hash-primitive)

tiger192-primitive

tiger192-primitiveprocedure

Returns the 192-bit Tiger hash primitive object.

Notes

Usage

(import tiger-hash)

Examples

(import tiger-hash message-digest-byte-vector)

(message-digest-string (tiger192-primitive) "abc")
