Chilkat Diffie-Hellman Objective-C Library is a simple library that allows two parties that have no prior knowledge of each other to jointly establish a shared secret key over an insecure communications channel.
This key can then be used to encrypt subsequent communications using a symmetric key cipher.
Here are some key features of "Chilkat Diffie-Hellman Objective-C Library":
Synonyms of Diffie-Hellman key exchange include:
· Diffie-Hellman key agreement
· Diffie-Hellman key establishment
· Diffie-Hellman key negotiation
· Exponential key exchange
Component Features:
· Simple 2-step Method for Computing a Shared Secret
· Safe prime generation. Generate new P and G values.
· Ability to use Known Primes from RFC 2409 and RFC 3526 (Oakley and MODP groups)
Limitations:
· 30 days trial.
What's New in This Release: [ read full changelog ]
· (backward compatibility) Removed the deprecated CkCrypt and CkFtp C++ classes. (CkCrypt2 and CkFtp2 have been the primary C++ classes for encryption and FTP for many years.)
· (backward compatibility) Removed the deprecated Chilkat.Crypt and Chilkat.Ftp .NET classes. (The primary Chilkat .NET classes for encryption and FTP have been Chilkat.Crypt2 and Chilkat.Ftp2 for many years.)
· (backward compatibility) Removed the "Blacklist" class wherever it may have been present. This class has been deprecated for many years, and the online documentation for it was removed many years ago.
· (backward compatibility, C++ API) All C++ method arguments that were pointers to objects have now become references to objects. For example, if a method argument was "CkCert *", it is now "CkCert &". This cause a compilation error, but the coding fix is very simple (just dereference the pointer that is passed). There are two exceptions. One is for CkXml::Search* methods where the 1st argument may be NULL...
