OpenKeychain

OpenKeychain


OpenKeychain helps you communicate more privately and securely. It uses high-quality modern encryption to ensure that your messages can be read only by the people you send them to, others can send you messages that only you can read, and these messages can be digitally signed so the people getting them are sure who sent them. OpenKeychain is based on the well established OpenPGP standard making encryption compatible across your devices and operating systems.

Modern encryption is based on digital “keys”. OpenKeychain stores and manages your keys, and those of the people you communicate with, on your Android. It also helps you find others’ keys online, and interchange keys by touching devices. But its most frequent use is in using those keys to encrypt and decrypt messages.

Great! A real 5-star app (similar to APG)- flexible & resilient tool. 4096bits RSA, (512SAH) & 256 AES, a combination of almost unbreakable cypher. You can encrypt msgs, emails, files etc ... exchange public keys with your secret lover ;-) & make the life of NSA difficult. Still, make sure that ur pw is at least 16 character (combination of all). It would be great if the app can only be accessed by a PW and a facility to clear all cached texts in the clipboard when exiting (it needs an exit function). Well done!
