50 created with the private EC key I<eckey>. To obtain the actual signature
54 I<dgst> using the private EC key I<eckey>. The DER encoded signatures is
56 point to ECDSA_size(eckey) bytes of memory. The parameter I<type> is currently
67 public key I<eckey>. The parameter I<type> is ignored.
78 I<eckey> is the private EC key and I<ctx> is a pointer to B<BN_CTX> structure
83 I<dgst> using the private EC key I<eckey> and the optional pre-computed values
85 length is returned in I<siglen>. Note: I<sig> must point to ECDSA_size(eckey)
