Module cryptoxide::hashing::sha1

An implementation of the SHA-1 cryptographic hash algorithm.

it is however discouraged to use this algorithm in any application as is, as this is not considered secured anymore. the algorithm is deprecated since 2011, and chosen prefix attack are practical.

However the hash function is still pervasively used in other contextes where security is still ok (e.g. hmac-sha1), so on this basis is available here.

Example

use cryptoxide::hashing::sha1;

let digest = sha1::Context::new().update(b"hello world").finalize();

Functions

sha1_digest_round_x4

Emulates llvm.x86.sha1rnds4 intrinsic. Performs 4 rounds of the message block digest.

sha1_first

Not an intrinsic, but gets the first element of a vector.

sha1_first_add

Not an intrinsic, but adds a word to the first element of a vector.

sha1_first_half

Emulates llvm.x86.sha1nexte intrinsic.

sha1_schedule_x4

Performs 4 rounds of the message schedule update.
