Field Documentation

◆ hmac_key_mode

otcrypto_key_mode_t hkdf_test_vector::hmac_key_mode

Key mode for HKDF (e.g.

HMAC-256). Determines hash function.

Definition at line 24 of file hkdf_functest.c.

◆ ikm

uint32_t* hkdf_test_vector::ikm

Input key derivation key (called IKM in RFC 5869).

Definition at line 28 of file hkdf_functest.c.

◆ ikm_bytelen

size_t hkdf_test_vector::ikm_bytelen

Length of key derivation key in bytes.

Definition at line 32 of file hkdf_functest.c.

◆ info

uint8_t* hkdf_test_vector::info

Context string.

May be NULL if salt_bytelen is 0.

Definition at line 44 of file hkdf_functest.c.

◆ info_bytelen

size_t hkdf_test_vector::info_bytelen

Length of info in bytes.

Definition at line 48 of file hkdf_functest.c.

◆ okm

uint32_t* hkdf_test_vector::okm

Expected output derived key (called OKM in RFC 5869).

Definition at line 65 of file hkdf_functest.c.

◆ okm_bytelen

size_t hkdf_test_vector::okm_bytelen

Length of derived key in bytes.

Definition at line 69 of file hkdf_functest.c.

◆ prk

uint32_t* hkdf_test_vector::prk

Expected value for the intermediate pseudo-random key.

This is the output of the extract phase and the input for the expand phase. Its length should be the same as the hash function digest length. Some test vectors may not include an expected value for the PRK, so if this pointer is NULL, the PRK will not be checked.

Definition at line 57 of file hkdf_functest.c.

◆ prk_wordlen

size_t hkdf_test_vector::prk_wordlen

Length of pseudo-random key in 32-bit words.

Definition at line 61 of file hkdf_functest.c.

◆ salt

uint8_t* hkdf_test_vector::salt

Salt value.
