Hex Editor Neo allows you to encrypt or decrypt binary/text file or just a part of it's data using any installed block or stream cipher, including: RSA Security RC2 (ARC2) or RC4 (Rivest Cipher 4 aka ARC4), Data Encryption Standard (DES) symmetric-key algorithm, two-key/three-key Tr...
Data encryption and decryption A whole document or a part of it may be encrypted and decrypted, using any installed block or stream cipher. Data Operations A large set of data operation (bitwise, arithmetic and shifts) are provided. File comparison Hex Editor provides two file comparison algorit...

Since no use is made of a possible presence of a (functional or non-functional) file system, the original file sizes are principally unknown to this algorithm, and so are the original filenames. That is why the resulting files are named according to the following pattern: Prefix[X]id0000...
Support of multiple number bases - Auto base-conversion on select - Support of numbers up to 4096 Bits 1. About RSA RSA is a Public Key Cryptosystem developed in 1977 by Ronald Rivest, Adi Shamir and Leonard Adleman. Since 09-20-2000 the U.S. Patent #4,405,829 on this Algorithm ...
