Contact PEA is a self-decrypting archive for showing and modifying encrypted contacts. The program supports many cloud providers. The shown address books are never stored unencrypted on your disk or in the cloud, but exist as plain text only in the memory (RAM). Contact PEA is compatible with many vCard applications, platform independent and Open Source. No installation or registration is required, only a Java Runtime Environment. Contact PEA uses authenticated encryption (EAX mode) and a memory-hard key derivation function (Catena) to prevent against custom-hardware attacks and tries to protect your privacy as much as possible.
