NAME Crypt::OpenSSL::Verify - OpenSSL Verify certificate verification in XS. SYNOPSIS use Crypt::OpenSSL::Verify; use Crypt::OpenSSL::X509; my $ca = Crypt::OpenSSL::Verify->new( 't/cacert.pem', # or undef { CApath => '/etc/ssl/certs', # Optional noCAfile => 1, # Optional noCApath => 0 # Optional } ); # Backward compatible with Crypt::OpenSSL:VerifyX509 my $ca = Crypt::OpenSSL::Verify->new('t/cacert.pem'); # Using the defaults of your OS: my $ca = Crypt::OpenSSL::Verify->new(); # and later on.. my $cert = Crypt::OpenSSL::X509->new(...); $ca->verify($cert); The object created is similar to running the following command with the "openssl verify" command line tool: "openssl verify [ -CApath /path/to/certs ] [ -noCApath ] [ -noCAfile ] [ -CAfile /path/to/file ] cert.pem" DESCRIPTION Given a CA certificate and another untrusted certificate, will show whether the CA signs the certificate. This is a useful thing to have if you're signing with X509 certificates, but outside of SSL. A specific example is where you're working with XML signatures, and need to verify that the signing certificate is valid. METHODS new() Constructor. Returns an OpenSSL Verify instance, set up with the given CA. my $ca = Crypt::OpenSSL::Verify->new( 't/cacert.pem', # or undef { # Path to a directory containg hashed CA Certificates CApath => $ca_path, # Default CAfile should not be loaded if TRUE, defaults to FALSE noCAfile => 0, # Default CApath should not be loaded if TRUE, defaults to FALSE noCApath => 0, # Do not override any OpenSSL verify errors if FALSE, defaults to TRUE strict_certs => 1, } ); # Backward compatible with Crypt::OpenSSL:VerifyX509 my $ca = Crypt::OpenSSL::Verify->new('t/cacert.pem', {strict_certs => 0 }); # Using the defaults of your OS: my $ca = Crypt::OpenSSL::Verify->new(); verify($cert) Verify the certificate is signed by the CA. Returns true if so, and croaks with the verification error if not. Arguments: * $cert - a Crypt::OpenSSL::X509 object for the certificate to verify. ctx_error_code($ctx) Calls the C code to obtain the OpenSSL error code of the verify and returns an integer value Arguments: * $ctx - a long unsigned integer containing the pointer to the X509_STORE_CTX that was passed to the callback function during the certificate verification register_verify_cb(\&verify_callback); Registers a Perl Sub as the callback function for OpenSSL to call during the registration process Arguments: * \&verify_callback - a reference to the verify_callback sub verify_callback($ok, $ctx) Called directly by OpenSSL and in the case of an acceptable error will change the response to 1 to signify no error Arguments: $ok - Error (0) or Success (1) from the OpenSSL certificate verification results $ctx - value of the pointer to the Certificate Store CTX used to access the error codes that OpenSSL returned AUTHOR Timothy Legge Wesley Schwengle COPYRIGHT The following copyright notice applies to all the files provided in this distribution, including binary files, unless explicitly noted otherwise.
