Struct ring::digest::Algorithm [−][src]
pub struct Algorithm {
pub output_len: usize,
pub chaining_len: usize,
pub block_len: usize,
// some fields omitted
}
Expand description
A digest algorithm.
Fields
output_len: usize
The length of a finalized digest.
chaining_len: usize
The size of the chaining value of the digest function, in bytes. For
non-truncated algorithms (SHA-1, SHA-256, SHA-512), this is equal to
output_len
. For truncated algorithms (e.g. SHA-384, SHA-512/256),
this is equal to the length before truncation. This is mostly helpful
for determining the size of an HMAC key that is appropriate for the
digest algorithm.
block_len: usize
The internal block length.
