Digest

[Source]

Produces a hash from the chunks of input. Feed the input with append() and produce a final hash from the concatenation of the input with final().

append() accumulates input; final() returns the hash of the concatenation, or raises. It never returns a hash of anything other than what was appended. Construction raises when OpenSSL fails to allocate a context; append() and final() raise when OpenSSL reports failure.

shake128

[Source]

SHAKE128 is an extendable output function (XOF) that can produce variable-length output. The size' parameter controls the output length in bytes (default: 16). Variable-length output requires OpenSSL 3.0.x or OpenSSL 4.0.x; on OpenSSL 1.1.x, only the default size is accepted.

new ref shake128(
  size': USize val = 16)
: Digest ref^ ?

Parameters

• size': USize val = 16

Returns

• Digest ref^ ?

---

shake256

[Source]

SHAKE256 is an extendable output function (XOF) that can produce variable-length output. The size' parameter controls the output length in bytes (default: 32). Variable-length output requires OpenSSL 3.0.x or OpenSSL 4.0.x; on OpenSSL 1.1.x, only the default size is accepted.

new ref shake256(
  size': USize val = 32)
: Digest ref^ ?

Parameters

• size': USize val = 32

Returns

• Digest ref^ ?

---

Public Functions

append

[Source]

Update the digest with input.

Raises an error when final() has already been called, and when OpenSSL could not take the input.

fun ref append(
  input: ByteSeq)
: None val ?

Parameters

• input: ByteSeq

Returns

• None val ?

---

final

[Source]

Return the hash of the input passed to append(). A second call returns the hash the first one produced.

Raises an error when OpenSSL could not produce the hash. A digest that raises here has no hash to give, and raises from every later call.

fun ref final()
: Array[U8 val] val ?

Returns

• Array[U8 val] val ?

---

digest_size

[Source]

Return the size of the message digest in bytes.

fun box digest_size()
: USize val

Returns

• USize val
