0.1.3 Added signature support using ED25519. Key format has changed it now contains the ed25519 public key part as well, required for signing. Key version is now 0x2 and vault version 0x2. There's no backwards compatibility, since this is still beta. Re-organized header files. Added support for self encryption using the users own key pair for encryption and decryption. Backport of issue https://github.com/zeromq/zeromq4-x/issues/29 Fixed key export, now uses big endianess as well. Updated POD documentation. Fixed a couple of minor bugs which lead to crashes. Options -r and -R exchanged: -R = remove key, -r = recipient. Added support for derived keys (using -r). 0.1.2 Fixed bug in pcp_derivekey() which derives encryption keys. it generated collisions due coding error, e.g. passphase 'a' resulted in the same encryptionkey as passphase 'r'. Now uses SHA256 witout the xor stuff, which was the cause for the bug. This also fixes a segmentation fault which occured invariably by entering an invalid passphrase. Added support for derived public keys using the -R option, which allows two peers to encrypt messages without the need to reveal their primary public keys. That way each peer will have another public key of the same source. Added more unit tests to reflect the above changes. 0.1.1 Changed output format of encrypted keys. now we encode it properly with the Z85 encoding and add a header and footer to it: -----BEGN CURVE25519 SECRET KEY----- 0q<1MspXp=x>mBZsUJF:2#)o*!.nTKR8SK}0IfuMBmC1a&*?)JD4%$%I5
