![]() This allows all the problems with a certificate chain to be determined. ![]() There is one crucial difference between the verify operations performed by the verify program: wherever possible an attempt is made to continue afterĪn error whereas normally the verify operation would halt on the first error. The verify program uses the same functions as the internal SSL and S/MIME verification, therefore this description applies to these If no certificate filenames are included then an attempt is made to read a certificate from standard input. This is useful if the first certificate filename begins with aĬertificates one or more certificates to verify. ![]() All arguments following this are assumed to be certificate files. This is disabled by default because it doesn't add any security. check_ss_sig Verify the signature on the self-signed root CA. use_deltas Enable support for delta CRLs. extended_crl Enable extended CRL features such as indirect CRLs and alternate CRL signing keys. x509_strict Disable workarounds for broken certificates which have to be disabled for strict X.509 compliance. If this option is set critical extensions are ignored. ignore_critical Normally if an unhandled critical extension is present which is not supported by OpenSSL the certificate is rejected (as required by RFC3280Įt al). crl_check_all Checks the validity of all certificates in the chain by attempting to lookup valid CRLs. crl_check Checks end entity certificate validity by attempting to lookup a valid CRL. policy_print Print out diagnostics, related to policy checking inhibit_map Set policy variable inhibit-policy-mapping (see RFC3280 et al). inhibit_any Set policy variable inhibit-any-policy (see RFC3280 et al). explicit_policy Set policy variable require-explicit-policy (see RFC3280 et al). policy_check Enables certificate policy processing. The policy arg can be an object nameĪn OID in numeric form. policy arg Enable policy processing and add arg to the user-initial-policy-set (see RFC3280 et al). However the presence of rejection messages does not itself imply that anything is wrong: during the normal verify process several rejections may take This shows why each candidate issuer certificate was issuer_checks print out diagnostics relating to searches for the issuer certificate of the current certificate. verbose print extra information about the operations being performed. See the VERIFY OPERATION section for more Sslserver, nssslserver, smimesign, smimeencrypt. Without this option no chain verification will be done. purpose purpose the intended use for the certificate. The file should contain multiple certificates untrusted file A file of untrusted certificates. The file should contain multiple certificates in PEM format concatenated together. CAfile file A file of trusted certificates. Symbolic links to a directory of certificates. Under Unix the c_rehash script will automatically create Hashed certificate subject name: see the -hash option of the x509 utility). The certificates should have names of the form: hash.0 or have symbolic links to them of this form ("hash" is the CApath directory A directory of trusted certificates. The verify command verifies certificate chains.
