    Overview

    package shake implements the SHAKE and cSHAKE XOF algorithm families.

    The SHA3 hash algorithm can be found in the crypto/sha3.

    Types

    Context ¶
    Source

    Context :: struct {
	st:             struct #raw_union {
		b: [200]u8,
		q: [25]u64,
	},
	pt:             int,
	rsiz:           int,
	mdlen:          int,
	dsbyte:         u8,
	is_initialized: bool,
	is_finalized:   bool,
}
     

    Context is a SHAKE128, SHAKE256, cSHAKE128, or cSHAKE256 instance.

    Procedures

    clone ¶
    Source

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

    clone clones the Context other into ctx.

    init_128 ¶
    Source

    init_128 :: proc(ctx: ^Context) {…}
     

    init_128 initializes a Context for SHAKE128.

    init_256 ¶
    Source

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

    init_256 initializes a Context for SHAKE256.

    init_cshake_128 ¶
    Source

    init_cshake_128 :: proc(ctx: ^Context, domain_sep: []u8) {…}
     

    init_cshake_128 initializes a Context for cSHAKE128.

    init_cshake_256 ¶
    Source

    init_cshake_256 :: proc(ctx: ^Context, domain_sep: []u8) {…}
     

    init_cshake_256 initializes a Context for cSHAKE256.

    read ¶
    Source

    read :: proc(ctx: ^Context, dst: []u8) {…}
     

    read reads output from the SHAKE instance. There is no practical upper limit to the amount of data that can be read from SHAKE. After read has been called one or more times, further calls to write will panic.

    reset ¶
    Source

    reset :: proc(ctx: ^Context) {…}
     

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

    write ¶
    Source

    write :: proc(ctx: ^Context, data: []u8) {…}
     

    write writes more data into the SHAKE instance. This MUST not be called after any reads have been done, and attempts to do so will panic.
