Trait Implementations

impl AlgorithmOID for SHA256

Assigned by NIST in the Computer Security Objects Register: id-sha256 { hashAlgs 1 }

const OID: &'static [u32]

The OID in component form – each u32 is one OID component.

const OID_DER: &'static [u8]

The OID in its DER-encoded form.

impl HashAlgParams for SHA256

const OUTPUT_LEN: usize = 32

The fixed output length of the hash function.

const BLOCK_LEN: usize = 64

The internal block length of the hash function, which is often used as a meta-parameter for determining the security strength of the hash function since this limits the internal collision resistance of the hash function.
