CryptoPad is a free replacement for the built-in MemoPad application with
encryption/decryption features.
As you could see, the 2.2 (for OS2.0 or above) and 3.6 (for OS3.0 or above) versions
are a major improvement compared to MemoPad. CryptoPad use the MemoPad database
to store, display, edit the non crypted memos and his own database for the crypted
memos. The crypted memos don't appear in Palm Desktop but are backup crypted on
PC in a .pdb file.
The synchronisation of non crypted memos with the native MemoPad application
allow users to take advantage of all the features given by MemoPad:
- automatic synchronisation with the PC and ability of seeing the records with
Palm Desktop software or others.
- backup on PC of the archived deleted records.
Moreover, the categories are also synchronised with both applications automatically.
A global password can be define so that it just has to be entered once when trying to decrypt or encrypt a memo for the first time and available for the whole session. Go in the Preferences form and you can define a global password, change it or remove it exactly as you do it in the Security application. If you define a global password, it will be asked once when you will try for the first time to decrypt or encrypt a memo. If you don't try to decrypt or encrypt a record during the session, this global password will never be asked. If the record was not crypted with the global password, the current password will be asked and when the edition is over, the memo is re-encrypted with the global password (and not with the current password). This memo is saved crytped on the PC so the safety is preserved.
CryptoPad supports also memo longer than 2ko up to 64ko and has many features to show/hide the lines in the edit form for those who don't like that, to move automatically the last consulted memo on top of the list or an option to choose in which categories the rotation (with hard key) goes through.
For OS3.0 users (or above), CryptoPad 3.6 is available. It includes all the functions of MemoPad (the security and the command bar functions for PalmOS3.5 users) but also a great font management that allow users to choose a separate font for each memo while editing and for each category in the main form.
CryptoPad uses the blowfish encryption routine, as written by Eric Young.
The application only use the cfb64 encryption mode, that allows for
encryption of arbitrary length data with a password of up to 448 bits. The
complet package can be compile on a whole variety of platform and can be
