Encryption/decryption utility (freeware)

What is EasyCrypt?
EasyCrypt is yet another application that allows you to encrypt your sensitive files. The thing that makes EasyCrypt different from other utilities is that it allows you to use the internal RAM disk on the Communicator for decrypting the files. This ensures that when you launch an encrypted file and your Communicator reboots, no unencrypted copies remain behind since the RAM disk is wiped clean on every reboot automatically.

EasyCrypt is freeware and was written for the 9300(i)/9500 range of Communicators.

How to use EasyCrypt
You can use EasyCrypt to encrypt, decrypt or wipe a file or entire folder. When an encrypted file is started from another application (for example by selecting it in FileManager), EasyCrypt will prompt for the password to decrypt the file, decrypt the file to temporary storage (RAM disk by default) and launch it with the application that was specified when the file was first encrypted. After that EasyCrypt will wait until the started application terminates, re-encrypt the file (but only if it was changed) and wipe the temporary decrypted copy.

IMPORTANT: No backdoors, no warranty
EasyCrypt uses the exact same encryption algorithm (RC4) that is used in Crypto for the Psion 5MX by Philipp Salvisberg (thanks to Philipp for making the source code of Crypto available). Like it's ER5 counterpart, EasyCrypt does not have any backdoors. That means that there is no master password which can be used to decrypt all EasyCrypt encrypted files. The only way to decrypt a file is to supply the password you used when you encrypted it. If you forget your password, there is nothing I can do to help you. If you use EasyCrypt, you do so at your own risk!
