    Procedures

    clone ¶
    Source

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

    clone clones the Context other into ctx.

    final ¶
    Source

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

    final finalizes the Context, writes the digest to hash, and calls reset on the Context.

    Iff finalize_clone is set, final will work on a copy of the Context, which is useful for for calculating rolling digests.

    init_224 ¶
    Source

    init_224 :: proc(ctx: ^Context_256) {…}
     

    init_224 initializes a Context_256 for SHA-224.

    init_256 ¶
    Source

    init_256 :: proc(ctx: ^Context_256) {…}
     

    init_256 initializes a Context_256 for SHA-256.

    init_384 ¶
    Source

    init_384 :: proc(ctx: ^Context_512) {…}
     

    init_384 initializes a Context_512 for SHA-384.

    init_512 ¶
    Source

    init_512 :: proc(ctx: ^Context_512) {…}
     

    init_512 initializes a Context_512 for SHA-512.

    init_512_256 ¶
    Source

    init_512_256 :: proc(ctx: ^Context_512) {…}
     

    init_512_256 initializes a Context_512 for SHA-512/256.

    reset ¶
    Source

    reset :: proc(ctx: ^$T) {…}
     

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

    update ¶
    Source

    update :: proc(ctx: ^$T, data: []u8) {…}
     

    update adds more data to the Context.
