NAME
kcapi_hkdf - Extract-and-Expand HKDF (RFC5869)
SYNOPSIS
|
ssize_t kcapi_hkdf(constĀ charĀ * hashname , constĀ uint8_tĀ * ikm , size_t ikmlen , constĀ uint8_tĀ * salt , uint32_t saltlen , constĀ uint8_tĀ * info , size_t infolen , uint8_tĀ * dst , size_t dlen ); |
ARGUMENTS
hashname
[in] kernel crypto API name of a keyed hash (e.g. hmac(sha1))
ikm
[in] Input Keying Material (IKM) -- must be provided
ikmlen
[in] IKM buffer length -- must be non-zero
salt
[in] salt buffer -- may be NULL
saltlen
[in] salt buffer length -- may be zero
info
[in] info buffer -- may be NULL
infolen
[in] info buffer length -- may be zero
dst
[out] Buffer to store the generated key in,
dlen
[in] Length of the dst buffer. This value defines the number of bytes generated by the KDF.
DESCRIPTION
Perform the key-derivation function according to RFC5869. The input data is defined in sections 2.2 und 2.3 of RFC5869.
return 0 upon success; a negative errno-style error code if an error occurred
