Encrypt using Cert to produce -----BEGIN PKCS7----- ... -----END PKCS7-----

See more Encryption Examples

Demonstrates how to encrypt using a certificate to produce output such as:

-----BEGIN PKCS7-----
MIIHPwYJKoZIhvcNAQcEoIIHMDCCBywC ...
...
...
-----END PKCS7-----

The certificate to be used is not your own, but the certificate of the intended recipient of the message. PowerBuilder
