structstd.crypto.onetimeauth[src]

MAC functions requiring single-use secret keys.

Container Types

Types

TypeGhash[src]

GHASH is a universal hash function that uses multiplication by a fixed parameter within a Galois field.

It is not a general purpose hash function - The key must be secret, unpredictable and never reused.

GHASH is typically used to compute the authentication tag in the AES-GCM construction.

Source Code

Source code
pub const Ghash = Hash(.big, true)

TypePolyval[src]

POLYVAL is a universal hash function that uses multiplication by a fixed parameter within a Galois field.

It is not a general purpose hash function - The key must be secret, unpredictable and never reused.

POLYVAL is typically used to compute the authentication tag in the AES-GCM-SIV construction.
