| 54 | .Sh NAME | ||

| 56 | .Nd check whether a certificate is a CA certificate | ||
| 57 | .Sh SYNOPSIS | ||
| 58 | .In openssl/x509v3.h | ||

| 62 | .Fc | ||
| 63 | .Sh DESCRIPTION | ||
| 64 | The | ||
| 65 | .Fn X509_check_ca | ||
| 66 | function checks whether the given certificate is a CA certificate, | ||
| 67 | that is, whether it can be used to sign other certificates. | ||
| 68 | .Sh RETURN VALUES | ||
| 69 | If | ||
| 70 | .Fa cert | ||
| 71 | is a CA certificate, a non-zero value is returned; 0 otherwise. | ||
| 72 | .Pp | ||
| 73 | The following return values identify specific kinds of CA certificates: | ||
| 74 | .Bl -tag -width 2n | ||
| 75 | .It 1 | ||
| 76 | an X.509 v3 CA certificate with | ||
| 77 | .Sy basicConstraints | ||
| 78 | extension CA:TRUE | ||
| 79 | .It 3 | ||
| 80 | a self-signed X.509 v1 certificate | ||
| 81 | .It 4 | ||
| 82 | a certificate with | ||
| 83 | .Sy keyUsage | ||
| 84 | extension with bit | ||
| 85 | .Sy keyCertSign | ||
| 86 | set, but without | ||
| 87 | .Sy basicConstraints | ||
| 88 | .It 5 | ||
| 89 | a certificate with an outdated Netscape Certificate Type extension telling | ||
| 90 | that it is a CA certificate | ||

| 101 | .Fn X509_check_ca | ||
| 102 | first appeared in OpenSSL 0.9.7f and has been available since | ||
| 103 | .Ox 3.8 . | ||
| 104 | .Sh BUGS | ||
| 105 | If | ||
| 106 | .Fn X509_check_ca | ||
| 107 | fails to cache X509v3 extension values, the return value may | ||
| 108 | be incorrect. | ||
| 109 | An application should | ||
| 110 | call | ||
| 111 | .Xr X509_check_purpose 3 | ||
| 112 | with a | ||
| 113 | .Fa purpose | ||
| 114 | argument of \-1, | ||
| 115 | ensuring that the X509v3 extensions are cached, | ||
| 116 | before calling | ||
| 117 | .Fn X509_check_ca . | ||
