Secure Text is a software utility oriented towards data encryption and protection. With it you can easily encrypt, without needing previous knowledge, any file on your hard drive, avoiding unwanted attention and unauthorized access.
For this, Secure Text uses a simple but very effective system of character replacement, substituting each character of the original text with others that are different. For example, the character "a" can be substituted by "xyx".
Secure Text is completely free and is very small. You won´t even notice it is on your hard drive.
