Sha512 structv0.1.0

pub struct Sha512 {
    // private fields
}

Structural Copy; copying takes an independent snapshot of the digest state.

Constructors

Sha512

pub func Sha512() -> Sha512

A SHA-512 state.

Returns: a hasher producing a 512-bit digest

Source

Associated functions

New384

pub func New384() -> Sha512

A SHA-384 state.

Returns: a hasher producing a 384-bit digest

Source

NewTrunc224

pub func NewTrunc224() -> Sha512

A SHA-512/224 state.

Returns: a hasher producing SHA-512/224

Source

NewTrunc256

pub func NewTrunc256() -> Sha512

A SHA-512/256 state.

Returns: a hasher producing SHA-512/256

Source

Implements Digest

Sha512 conforms to Digest.

Update

pub func Update(self: &var Sha512, bytes: char8[..])

Adds bytes to the message.

Source

Finish

pub func Finish(self: &var Sha512, into: var char8[..])

Writes the digest into into. The padding carries a hundred and twenty eight bit length, so the final block needs seventeen free bytes rather than nine; a block with fewer takes a whole further block.

Source

DigestLength

pub func DigestLength(self: &Sha512) -> uint

Sixty-four, forty-eight, thirty-two or twenty-eight bytes, depending on which variant this is.

Returns: how many bytes a digest occupies

Source

BlockLength

pub func BlockLength(self: &Sha512) -> uint

A hundred and twenty eight bytes, for every variant.

Returns: how many bytes the compression function consumes at a time
