7 ECDSA_do_sign_ex - deprecated low-level elliptic curve digital signature algorithm
49 ECDSA_size() returns the maximum length of a DER encoded ECDSA signature
50 created with the private EC key I<eckey>. To obtain the actual signature
53 ECDSA_sign() computes a digital signature of the I<dgstlen> bytes hash value
60 ECDSA_do_sign() is similar to ECDSA_sign() except the signature is returned
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
69 ECDSA_do_verify() is similar to ECDSA_verify() except the signature is
73 during signature computation. Most applications will never need to call these
82 ECDSA_sign_ex() computes a digital signature of the I<dgstlen> bytes hash value
84 I<kinv> and I<rp>. The DER encoded signature is stored in I<sig> and its
88 ECDSA_do_sign_ex() is similar to ECDSA_sign_ex() except the signature is
93 ECDSA_size() returns the maximum length signature or 0 on error.
102 signature, 0 for an invalid signature and -1 on error.
107 Creating an ECDSA signature of a given SHA-256 hash value using the
124 Second step: compute the ECDSA signature of a SHA-256 hash value
142 Third step: verify the created ECDSA signature using ECDSA_do_verify():
153      /* signature ok */
155      /* incorrect signature */
