Fields

algorithm: usize

The hash algorithm.

prk: *const u8

The pointer to the pseudo random key.

prk_len: usize

The length of the pseudo random key.

Must be at least the length of the hash algorithm output.

info: *const u8

The pointer to the info.

May be null if [info_len] is null.

info_len: usize

The length of the info.

May be zero.

okm: *mut u8

The pointer to the output key material.

okm_len: usize

The length of the output key material.

Must be at most 255 times the output length of the hash algorithm.
