SerCrypt

The SerCrypt application was deveoped to be a tiny tool for a specific task: It keeps a text file secure. It's ideal for carrying your passwords and private text with you in a flash drive.

The tool has no setup, has one executable that you can copy to a flash disk or any directory in your system. Once it's opened it checks for data file, if not it asks you to create a password for its data file. After that the UI comes with an empty text area. You can enter as much text as you want here. Once done, just exit the program and it saves the text to the same directory (filename is default.bin). The encryption it uses is Rijndael 256 bits SHA1.

Be aware that once you create the file and exit the program, there is no way to recover the encrypted text if you forgot your password. Please make sure that the password works fine after deleting the originals.
