“Cryptlib’s high-level functions enable me to effect complex S/MIME
transformations with less setup and fewer function calls than other S/MIME
products I considered. At the same time, access to its low-level properties
and functions is invaluable in determining during interoperability testing
exactly where encryption, signing, and certificate problems lie.
Peter Gutmann, the developer, has always responded quickly and usefully to
my comments and questions. The few enhancements I requested (e.g. InterBase support) were provided quickly and correctly. Cryptlib should be the reference standard for security toolkits.”
