printcert
-printcert {-file cert_file}
{-v} {-Jjavaoption}
Reads the certificate from the file cert_file, and prints its contents in a human-readable format. If no file is given, the certificate is read from stdin.
The certificate may be either binary encoded or in printable encoding format, as defined by the Internet RFC 1421 standard.
Note: This option can be used independently of a keystore.
