 =head1 DESCRIPTION
 
 The EVP signature routines are a high level interface to digital
 signatures.

+EVP_SignInit_ex() sets up signing context I<ctx> to use digest
+I<type> from B<ENGINE> I<impl>. I<ctx> must be created with
 EVP_MD_CTX_new() before calling this function.
 
-EVP_SignUpdate() hashes B<cnt> bytes of data at B<d> into the
-signature context B<ctx>. This function can be called several times on the
-same B<ctx> to include additional data.
+EVP_SignUpdate() hashes I<cnt> bytes of data at I<d> into the
+signature context I<ctx>. This function can be called several times on the

-EVP_SignFinal() signs the data in B<ctx> using the private key B<pkey> and

-EVP_SignInit() initializes a signing context B<ctx> to use the default

-EVP_PKEY_size() returns the maximum size of a signature in bytes. The actual
-signature returned by EVP_SignFinal() may be smaller.
-
-EVP_PKEY_security_bits() returns the number of security bits of the given B<pkey>,
-bits of security is defined in NIST SP800-57.

 EVP_SignInit_ex(), EVP_SignUpdate() and EVP_SignFinal() return 1
