Bytes to Numbers or Alpha.zip - Chuck Mire 0 /10
Bytes to Numbers or Alpha & Numbers or Alpha to Bytes.exe is a Windows executable program to encrypt any file into a disk file with a format of EITHER: ALL numbers; ALL upper case letters; or ALL lower case letters. In addition, there are two choices for the encryption procedure: AWC/SWB (Add Without Carry/Subtract Without Borrow) or XOR (Exclusive OR). To decrypt the file, one needs to know which procedure was used as well as (1) a random NUMBER of up to seven digits (including negative numbers and/or decimals) AND (2) an OFFSET into the random stream. The file may either be decrypted into a NEW disk file (it will NOT overwrite an existing file) OR decrypted only to the screen (NO disk write). The length of the encrypted file created by this program is determined by the encryption procedure, random NUMBER and the OFFSET into the random stream. Each of the bytes are encrypted into a varying-length number/alpha from 3 to 9 bytes in length. This means that there will be different (asymmetrical) encrypted file lengths that are unique. The attached zip file contains the source code, the compiled Windows executable, a command line batch file, and a PDF File which contains other abilities of this program (such as decrypting concatenated files) as well as explanatory screen shots.
