Hi, Can you help me? How can I extract the signature value from the certificate X.509? Thanks Previous Comments: ------------------------------------------------------------------------ [2007-01-11 14:33:01] bassijunior at yahoo dot com dot br Ok. Thanks for the answer. Maybe, I have to use this function. But, how can extract the signature value from the certificate X.509? I already tried the openssl_x509_parse, but I didn't get the signature value. I have the certificate in the format .PEM, like this: -----BEGIN CERTIFICATE----- MIIDRDCCAq2gAwIBAgIERaJ12TANBgkqhkiG9w0BAQUFADB6MQswCQYDVQQGEwJC UjELMAkGA1UECBMCUkoxFzAVBgNVBAcTDlJpbyBkZSBKYW5laXJvMRwwGgYDVQQD FBNBR0MgLSBQcm9qZXRvX0ZpbmFsMScwJQYJKoZIhvcNAQkBFhhiYXNzaWp1bmlv ckB5YWhvby5jb20uYnIwHhcNMDcwMTA4MTY0ODI1WhcNMDgwMTA4MTY0ODI1WjCB 1DELMAkGA1UEBhMCQlIxCzAJBgNVBAgTAlJKMQ0wCwYDVQQHEwRSaW8gMRwwGgYD VQQDExNKb3NlIEFsYmVydG86MzI0MzQzMWUwYwYDVQRBE1xBcnF1aXZvOiBiYWNr MS5qcGcsIEhhc2g6IGRmNjVmZDFlOTcwM2Q2MTM1ZWU2NjNhNjlkZDA4NTJjYzZj MTU1ZjEsIElQIGRvIHVzdWFyaW86IDEyNy4wLjAuMTEkMCIGCSqGSIb3DQEJARYV YmFzc2lqdW5pb3JAZ21haWwuY29tMIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKB gQC+/l11fmU8ZsipmXA+oBKQml6dpHupANKOiR/NUynn3g3+TVeBi8LOu5zLz1V9 4Qj8STvzepoxsJ/uuIhieS9sPtu4Erg5Xi4QvEZPRCxzzTH6237z924sFK+RjiaA Oz7voL48y6+EWzdlX81fCUADsA1ps3AgTm2nICldPNWqhwIDAQABo3wwejAJBgNV HRMEAjAAMC0GCWCGSAGG+EIBDQQgFh5DZXJ0aWZpY2FkbyBmaW5hbCBwYXJhIHVz dWFyaW8wHQYDVR0OBBYEFHz+89um4yL1HYMzCJqVldQ9w4QnMB8GA1UdIwQYMBaA FLRXYeje0vAjbdOpIQmMW5EzaQEpMA0GCSqGSIb3DQEBBQUAA4GBAMffIowvU8K5 Q5xyNt7MyTpH/2GtO01bPlrXxEP8XJVHQS9UK7F4lRks6lSmN4yNrbmgiO94JbzM 6xdaH3EofROnMKT/A4SMbpUNNUDClC+DiSBWw3mN+3D2wzakLrCszXrqe21dO1fC 0JB5xjnKJjvZtdLD7/s87eCUNntaN81E -----END CERTIFICATE----- I need to verify a certificate X.509.
