Documentation

An implementation of the RIPE cryptographic hash function.

See message-digest-primitive for more information.

RIPE 128 API

Component export

Usage

 
(import ripemd128-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

[procedure] (init CTX)

Initializes a RIPEMD128 CTX, with at least context-size byte size.

update

[procedure] (update CTX OBJ LEN)

Accumulate LEN bytes from the Scheme OBJ into CTX.

raw-update

[procedure] (raw-update CTX PTR LEN)

Accumulate LEN bytes from the byte PTR into CTX.

final

[procedure] (final CTX OBJ)

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

RIPE 128 Primitive

Packaged export

Usage

 
(import ripemd128-primitive)

ripemd128-primitive

[procedure] (ripemd128-primitive) -> message-digest-primitive

Returns the 128-bit RIPE message-digest-primitive object.

RIPE 160 API

Component export

Usage

 
(import ripemd160-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

[procedure] (init CTX)

Initializes a RIPEMD-160 CTX, with at least context-size byte size.

update

[procedure] (update CTX OBJ LEN)

Accumulate LEN bytes from the Scheme OBJ into CTX.

raw-update

[procedure] (raw-update CTX PTR LEN)

Accumulate LEN bytes from the byte PTR into CTX.

final

[procedure] (final CTX OBJ)

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

RIPE 160 Primitive

Packaged export

Usage

 
(import ripemd160-primitive)

ripemd160-primitive

[procedure] (ripemd160-primitive) -> message-digest-primitive

Returns the 160-bit RIPE message-digest-primitive object.

Usage

 
(import ripemd)

Examples

 
(import ripemd160-primitive message-digest-byte-vector)

(message-digest-string (ripemd160-primitive) "abc")
;=> "8eb208f7e05d987a9b044a8e98c6b087f15a0bfc"
