S/MIME Secure Email Systems

cryptlib employs the IETF-standardised Cryptographic Message Syntax (CMS, formerly called PKCS #7) format as its native data format. CMS is the underlying format used in the S/MIME secure mail standard, as well as a number of other standards covering secure EDI and related systems like HL7 medical messaging and the Session Initiation Protocol (SIP) for services like Internet telephony and instant messaging.

The complexity of the S/MIME format means that the few other toolkits that are available require a high level of programmer knowledge of S/MIME processing issues. In contrast cryptlib’s enveloping interface makes the process as simple as pushing raw data into an envelope and popping the processed data back out, a total of three function calls, plus one more call to add the appropriate encryption or signature key.
