Description
This command processes PKCS#7 files. Note that it only understands PKCS#7 v 1.5 as specified in IETF RFC
2315. It cannot currently parse CMS as described in IETF RFC 2630.
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
History
The -engine option was deprecated in OpenSSL 3.0.
Name
openssl-pkcs7 - PKCS#7 command
Options
-help
