50 created with the private EC key I<eckey>. To obtain the actual signature
51 size use L<EVP_PKEY_sign(3)> with a NULL I<sig> parameter.
53 ECDSA_sign() computes a digital signature of the I<dgstlen> bytes hash value
54 I<dgst> using the private EC key I<eckey>. The DER encoded signatures is
55 stored in I<sig> and its length is returned in I<sig_len>. Note: I<sig> must
56 point to ECDSA_size(eckey) bytes of memory. The parameter I<type> is currently
57 ignored. ECDSA_sign() is wrapper function for ECDSA_sign_ex() with I<kinv>
58 and I<rp> set to NULL.
62 is a wrapper function for ECDSA_do_sign_ex() with I<kinv> and I<rp> set to
65 ECDSA_verify() verifies that the signature in I<sig> of size I<siglen> is a
66 valid ECDSA signature of the hash value I<dgst> of size I<dgstlen> using the
67 public key I<eckey>. The parameter I<type> is ignored.
72 The remaining functions utilise the internal I<kinv> and I<r> values used
75 either I<kinv> or I<r> is not NULL.
78 I<eckey> is the private EC key and I<ctx> is a pointer to B<BN_CTX> structure
79 (or NULL). The precomputed values or returned in I<kinv> and I<rp> and can be
82 ECDSA_sign_ex() computes a digital signature of the I<dgstlen> bytes hash value
83 I<dgst> using the private EC key I<eckey> and the optional pre-computed values
84 I<kinv> and I<rp>. The DER encoded signature is stored in I<sig> and its
85 length is returned in I<sig_len>. Note: I<sig> must point to ECDSA_size(eckey)
86 bytes of memory. The parameter I<type> is ignored.
