ESE

This is software used to encrypt files and directory contents on a computer disk. The program works based on the encryption algorithm version EN201. It is a symmetric substitution method of encryption. In the future, it is planned to extend this algorithm to an asymmetric method with a combination of substitution and transposition ciphers. Plus this algorithm is equipped with a hashing function to ensure that the decryption error is detected. ESE has the following features:

• encryption of files and directory contents using a key chosen by the user
• static file encryption - encryption is performed, according to 4 keys, whose length is around 256b
• File encryption unidirectional - complete destruction of the file and prevention of reading or restoring it
• Decryption of all mentioned methods
• Generation of security keys 32 - 4096b
• File fingerprinting.
