[−][src]Module ring::digest

SHA-2 and the legacy SHA-1 digest algorithm.

If all the data is available in a single contiguous slice then the digest function should be used. Otherwise, the digest can be calculated in multiple steps using Context.

Structs

Algorithm	A digest algorithm.
Context	A context for multi-step (Init-Update-Finish) digest calculations.
Digest	A calculated digest value.

Constants

MAX_BLOCK_LEN	The maximum block length (`Algorithm::block_len`) of all the algorithms in this module.
MAX_CHAINING_LEN	The maximum chaining length (`Algorithm::chaining_len`) of all the algorithms in this module.
MAX_OUTPUT_LEN	The maximum output length (`Algorithm::output_len`) of all the algorithms in this module.
SHA1_OUTPUT_LEN	The length of the output of SHA-1, in bytes.
SHA256_OUTPUT_LEN	The length of the output of SHA-256, in bytes.
SHA384_OUTPUT_LEN	The length of the output of SHA-384, in bytes.
SHA512_OUTPUT_LEN	The length of the output of SHA-512, in bytes.
SHA512_256_OUTPUT_LEN	The length of the output of SHA-512/256, in bytes.

Statics

SHA1_FOR_LEGACY_USE_ONLY	SHA-1 as specified in FIPS 180-4. Deprecated.
SHA256	SHA-256 as specified in FIPS 180-4.
SHA384	SHA-384 as specified in FIPS 180-4.
SHA512	SHA-512 as specified in FIPS 180-4.
SHA512_256	SHA-512/256 as specified in FIPS 180-4.

Functions
