Malcolm Bryant and FreEPOC present jRC4, a small file encryption utility written in Personal Java. It will encode and decode files using the secure RC4 algorithm on your P800, PC or other compatible Java machine.

jRC4 can protect your sensitive data. It was particularly written for users of the P800 smartphone, so that sensitive data which has been downloaded from a PC (for example Word or Excel files) can be encrypted to protect the contents should your smartphone be lost. However with knowledge of the original password, the contents can easily be decrypted and viewed on the P800 Viewer.

Unlike some other protection software written for PDAs which uses proprietory file formats, jRC4 will encrypt or decrypt any file. Because jRC4 runs on a number of different platforms (anything which runs Personal Java) you can always access your data.
