Add a Decryption Certificate

See more MIME Examples

Loads a CMS/PKCS #7 encrypted S/MIME message and decrypts it back to the original MIME content.

AddDecryptCert adds a certificate (with private key access) to the collection Chilkat searches when decrypting. Call it once for each candidate certificate.

The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

integer li_Success
