When I enter my master password into Espionage it thinks for a long while and eventually gives me a database decryption error and tells me to look in the log.
This is what I'm seeing;
6/1/12 6:15:36.235 PM Espionage ERROR (-[NSData(TECrypto) decrypt:]:131): scryptdec_buf returned: 9
6/1/12 6:15:36.235 PM Espionage ERROR (+[DBSubdb subdbWithData:master:pass:error:]:45): failed because: !decrypted
