EVP_PKEY_sign() does not hash the data to be signed, and therefore is
normally used to sign digests. For signing arbitrary messages, see the
-L<EVP_DigestSignInit(3)|EVP_DigestSignInit(3)> and
-L<EVP_SignInit(3)|EVP_SignInit(3)> signing interfaces instead.
+L<EVP_DigestSignInit(3)> and
+L<EVP_SignInit(3)> signing interfaces instead.
After the call to EVP_PKEY_sign_init() algorithm specific control
operations can be performed to set any appropriate parameters for the
-operation (see L<EVP_PKEY_CTX_ctrl(3)|EVP_PKEY_CTX_ctrl(3)>).
+operation (see L<EVP_PKEY_CTX_ctrl(3)>).
The function EVP_PKEY_sign() can be called more than once on the same
context if several operations are performed using the same parameters.
