Crate sha1

A minimal implementation of SHA1 for rust.

This implementation supports no_std which is the default mode. The following features are available and can be optionally enabled:

• serde: when enabled the Digest type can be serialized.
• std: when enabled errors from this library implement std::error::Error and the hexdigest shortcut becomes available.

Note: future versions of this crate with the old code are now under sha1_smol, the sha1 crate name with versions beyond the 0.6 line now refer to the RustCrypto implementation.

Example

let mut m = sha1_smol::Sha1::new();
m.update(b"Hello World!");
assert_eq!(m.digest().to_string(),
           "2ef7bde608ce5404e97d5f042f95f89f1c232871");

The sha1 object can be updated multiple times. If you only need to use it once you can also use shortcuts (requires std):

assert_eq!(sha1_smol::Sha1::from("Hello World!").hexdigest(),
           "2ef7bde608ce5404e97d5f042f95f89f1c232871");

Structs

Digest

Digest generated from a Sha1 instance.

DigestParseError

Indicates that a digest couldn’t be parsed.

Sha1

Represents a Sha1 hash object in memory.

Constants

DIGEST_LENGTH

The length of a SHA1 digest in bytes
