|
||
|
|
The \fBEVP_PKEY_new()\fR function allocates an empty \fB\s-1EVP_PKEY\s0\fR structure which is
|
||
|
|
used by OpenSSL to store public and private keys. The reference count is set to
|
||
|
|
\&\fB1\fR.
|
||
|
|
.PP
|
||
|
|
\&\fBEVP_PKEY_up_ref()\fR increments the reference count of \fBkey\fR.
|
||
|
|
.PP
|
||
|
|
\&\fBEVP_PKEY_free()\fR decrements the reference count of \fBkey\fR and, if the reference
|
||
|
|
count is zero, frees it up. If \fBkey\fR is \s-1NULL,\s0 nothing is done.
|
||
|
|
.PP
|
||
|
|
\&\fBEVP_PKEY_new_raw_private_key()\fR allocates a new \fB\s-1EVP_PKEY\s0\fR. If \fBe\fR is non-NULL
|
||
|
|
then the new \fB\s-1EVP_PKEY\s0\fR structure is associated with the engine \fBe\fR. The
|
||
|
|
\&\fBtype\fR argument indicates what kind of key this is. The value should be a \s-1NID\s0
|
||
|
|
for a public key algorithm that supports raw private keys, i.e. one of
|
||
|
|
\&\fB\s-1EVP_PKEY_HMAC\s0\fR, \fB\s-1EVP_PKEY_POLY1305\s0\fR, \fB\s-1EVP_PKEY_SIPHASH\s0\fR, \fB\s-1EVP_PKEY_X25519\s0\fR,
|
||
|
|
\&\fB\s-1EVP_PKEY_ED25519\s0\fR, \fB\s-1EVP_PKEY_X448\s0\fR or \fB\s-1EVP_PKEY_ED448\s0\fR. \fBkey\fR points to the
|
||
|
|
raw private key data for this \fB\s-1EVP_PKEY\s0\fR which should be of length \fBkeylen\fR.
|
||
|
|
The length should be appropriate for the type of the key. The public key data
|
||
|
|
will be automatically derived from the given private key data (if appropriate
|
||
|
|
for the algorithm type).
|
||
|
|
.PP
|
||
|
|
\&\fBEVP_PKEY_new_raw_public_key()\fR works in the same way as
|
||
|
|
\&\fBEVP_PKEY_new_raw_private_key()\fR except that \fBkey\fR points to the raw public key
|
||
|
|
data. The \fB\s-1EVP_PKEY\s0\fR structure will be initialised without any private key
|
||
|
|
information. Algorithm types that support raw public keys are
|
||
|
|
\&\fB\s-1EVP_PKEY_X25519\s0\fR, \fB\s-1EVP_PKEY_ED25519\s0\fR, \fB\s-1EVP_PKEY_X448\s0\fR or \fB\s-1EVP_PKEY_ED448\s0\fR.
|
||
|
|
.PP
|
||
|
|
\&\fBEVP_PKEY_new_CMAC_key()\fR works in the same way as \fBEVP_PKEY_new_raw_private_key()\fR
|
||
|
|
except it is only for the \fB\s-1EVP_PKEY_CMAC\s0\fR algorithm type. In addition to the
|
||
|
|
raw private key data, it also takes a cipher algorithm to be used during
|
||
|
|
creation of a \s-1CMAC\s0 in the \fBcipher\fR argument.
|
||
|
|
.PP
|
||
|
|
\&\fBEVP_PKEY_new_mac_key()\fR works in the same way as \fBEVP_PKEY_new_raw_private_key()\fR.
|
||
|
|
New applications should use \fBEVP_PKEY_new_raw_private_key()\fR instead.
|
||
|
|
.PP
|
||
|
|
\&\fBEVP_PKEY_get_raw_private_key()\fR fills the buffer provided by \fBpriv\fR with raw
|
||
|
|
private key data. The size of the \fBpriv\fR buffer should be in \fB*len\fR on entry
|
||
|
|
to the function, and on exit \fB*len\fR is updated with the number of bytes
|
||
|
|
actually written. If the buffer \fBpriv\fR is \s-1NULL\s0 then \fB*len\fR is populated with
|
||
|
|
the number of bytes required to hold the key. The calling application is
|
||
|
|
responsible for ensuring that the buffer is large enough to receive the private
|
||
|
|
key data. This function only works for algorithms that support raw private keys.
|
||
|
|
Currently this is: \fB\s-1EVP_PKEY_HMAC\s0\fR, \fB\s-1EVP_PKEY_POLY1305\s0\fR, \fB\s-1EVP_PKEY_SIPHASH\s0\fR,
|
||

\&\fB\s-1EVP_PKEY_X25519\s0\fR, \fB\s-1EVP_PKEY_ED25519\s0\fR, \fB\s-1EVP_PKEY_X448\s0\fR or \fB\s-1EVP_PKEY_ED448\s0\fR.
|
||
|
|
.PP
|
||
|
|
\&\fBEVP_PKEY_get_raw_public_key()\fR fills the buffer provided by \fBpub\fR with raw
|
||
|
|
public key data. The size of the \fBpub\fR buffer should be in \fB*len\fR on entry
|
||
|
|
to the function, and on exit \fB*len\fR is updated with the number of bytes
|
||
|
|
actually written. If the buffer \fBpub\fR is \s-1NULL\s0 then \fB*len\fR is populated with
|
||
|
|
the number of bytes required to hold the key. The calling application is

||
|
|
responsible for ensuring that the buffer is large enough to receive the public
|
||
|
|
key data. This function only works for algorithms that support raw public keys.

Currently this is: \fB\s-1EVP_PKEY_X25519\s0\fR, \fB\s-1EVP_PKEY_ED25519\s0\fR, \fB\s-1EVP_PKEY_X448\s0\fR or
