This implementation is allocation-free, compile-time friendly, and supports incremental updates.

Use update to feed bytes and finalize to consume the state and return the digest.

Generated with digest!.

Implementations

impl Md5

pub const DIGEST_LEN: usize = 16

The digest size in bytes.

pub const BLOCK_LEN: usize = 64

The internal block size in bytes.

pub const fn new() -> Md5

Creates a new MD5 state.

pub const fn len_bits(&self) -> u64

Returns the number of message bits already accepted.

pub const fn is_empty(&self) -> bool

Returns true if no message bytes have been accepted.

pub const fn reset(&mut self)

Resets the state to its initial value.

pub const fn update(&mut self, bytes: &[u8]) -> Result<(), CryptoError>

Updates the digest state with bytes.

Errors

Returns LengthOverflow if the total message length would exceed MD5’s 64-bit bit-length field.

pub const fn digest_bytes( bytes: &[u8], ) -> Result<Digest<{ Md5::DIGEST_LEN }>, CryptoError>

Computes the MD5 digest of bytes.

Errors

Returns LengthOverflow if bytes exceeds MD5’s supported message length.

pub const fn hmac( key: &[u8], message: &[u8], ) -> Result<Digest<{ Md5::DIGEST_LEN }>, CryptoError>

Computes the HMAC of message using the given key.

If the key is longer than the block size, it is first hashed.

Errors

Returns LengthOverflow if key hashing or the inner/outer digest computation exceeds the hash input length limit.

pub const fn finalize(self) -> Digest<{ Md5::DIGEST_LEN }>

Finalizes the digest and consumes the state.

This method cannot fail.
