pkcs7(1ssl) pkcs7(1ssl) NAME pkcs7 - PKCS#7 utility SYNOPSIS openssl pkcs7 [-inform PEM | DER] [-outform PEM | DER] [-in filename] [-out filename] [-print_certs] [-text] [-noout] OPTIONS Specifies the input format. The DER format is DER encoded PKCS#7 v1.5 structure. The PEM format (the default) is a base64 encoded version of the DER form with header and footer lines. Specifies the output for‐ mat. The options have the same meaning as the -inform option. Speci‐ fies the input filename to read from or standard input if this option is not specified. Specifies the output filename to write to or stan‐ dard output by default. Prints out any certificates or CRLs contained in the file. They are preceded by their subject and issuer names in one-line format. Prints out certificate details in full rather than just subject and issuer names. Does not output the encoded version of the PKCS#7 structure (or certificates if -print_certs is set). DESCRIPTION The pkcs7 command processes PKCS#7 files in DER or PEM format. NOTES The PEM PKCS#7 format uses the header and footer lines: -----BEGIN PKCS7----- -----END PKCS7----- For compatability with some CAs it will also accept: -----BEGIN CERTIFICATE----- -----END CERTIFICATE----- RESTRICTIONS There is no option to print out all the fields of a PKCS#7 file. These PKCS#7 routines only understand PKCS#7 v 1.5 as specified in RFC2315. For example, they cannot currently parse the new CMS as described in RFC2630. EXAMPLES Convert a PKCS#7 file from PEM to DER: openssl pkcs7 -in file.pem -outform DER -out file.der Output all certificates in a file: openssl pkcs7 -in file.pem -print_certs -out certs.pem SEE ALSO Commands: crl2pkcs7(1ssl) pkcs7(1ssl)[top]
