| 73 | .Sh DESCRIPTION | ||
| 74 | .Fn DSA_do_sign | ||
| 75 | computes a digital signature on the | ||
| 76 | .Fa dlen | ||
| 77 | byte message digest | ||
| 78 | .Fa dgst | ||
| 79 | using the private key | ||
| 80 | .Fa dsa | ||
| 81 | and returns it in a newly allocated | ||
| 82 | .Vt DSA_SIG | ||
| 83 | structure. | ||
| 84 | .Pp | ||
| 85 | .Xr DSA_sign_setup 3 | ||
| 86 | may be used to precompute part of the signing operation in case | ||
| 87 | signature generation is time-critical. | ||
| 88 | .Pp | ||
| 89 | .Fn DSA_do_verify | ||
| 90 | verifies that the signature | ||
| 91 | .Fa sig | ||
| 92 | matches a given message digest | ||
| 93 | .Fa dgst | ||
| 94 | of size | ||
| 95 | .Fa dgst_len . | ||
| 96 | .Fa dsa | ||
| 97 | is the signer's public key. | ||
| 98 | .Sh RETURN VALUES | ||
| 99 | .Fn DSA_do_sign | ||
| 100 | returns the signature or | ||
| 101 | .Dv NULL | ||
| 102 | on error. | ||
| 103 | .Fn DSA_do_verify | ||
| 104 | returns 1 for a valid signature, 0 for an incorrect signature, | ||
| 105 | and -1 on error. | ||
| 106 | The error codes can be obtained by | ||
| 107 | .Xr ERR_get_error 3 . | ||
