| 71 | .Sh DESCRIPTION | ||
| 72 | .Fn X509_get0_signature | ||
| 73 | sets | ||
| 74 | .Pf * Fa psig | ||
| 75 | to the signature of | ||
| 76 | .Fa x | ||
| 77 | and | ||
| 78 | .Pf * Fa palg | ||
| 79 | to the signature algorithm of | ||
| 80 | .Fa x . | ||
| 81 | The values returned are internal pointers | ||
| 82 | that must not be freed by the caller. | ||
| 83 | .Pp | ||
| 84 | .Fn X509_get_signature_nid | ||
| 85 | returns the NID corresponding to the signature algorithm of | ||
| 86 | .Fa x . | ||
| 87 | .Pp | ||
| 88 | These functions provide lower level access to the signature | ||
| 89 | for cases where an application wishes to analyse or generate a | ||
| 90 | signature in a form where | ||
| 91 | .Xr X509_sign 3 | ||
| 92 | is not appropriate, for example in a non-standard or unsupported format. | ||
