BLOCK_SIZE #

Source

DIGEST_SIZE :: 20

DIGEST_SIZE is the SHA1 digest size in bytes.

Procedures

5

clone #

Source 
clone :: proc(ctx, other: ^$T) {…}

clone clones the Context other into ctx.

final #

Source 
final :: proc(ctx: ^Context, hash: []u8, finalize_clone: bool = false) {…}

final finalizes the Context, writes the digest to hash, and calls reset on the Context. If and only if (⟺) finalize_clone is set, final will work on a copy of the Context, which is useful for for calculating rolling digests.

reset #

Source 
reset :: proc(ctx: ^$T) {…}

reset sanitizes the Context. The Context must be re-initialized to be used again.
