FileHashler is a security utility program capable to transfer any single file
Edit by : FileHashler is a security utility program capable to transfer any single file (up to 2,1 GB) into an encrypted form and back from an encrypted form into the cleartext form. This service protects the contents of the file to be seen by unauthorised readers. Authorised access to an encrypted file is checked through a symmetric user keyword or PassPhrase. Symmetric hereby means that you use the same key to Encrypt and Decrypt the file. Such a key is also named a secret key. Decryption performs FAIL-safe; that means the utility authenticates legitimate access by the key value and will not produce any results if access fails to be legitimate.

Basically encrypted file and cleartext file are designed to coexist while the utility makes some effort to keep namespaces of both file types separated. There is an option, however, by which the cleartext file can get erased in a safe way after encryption is completed.

-- Self-Documentation and Archive Feature FileHashler encrypted files store internal information about the original file they keep transformed. This comprises the cleartext files cataloging information as well as an optional user comment about it. The utility has a Verify function which controls data integrity of the encrypted file and shows a PrintOut of the information about the contained cleartext file. Only authenticated access can perform this function. By this it is possible to use FileHashler files as shrowded archive files including an integrity validation functionality. E.g. you may change the filename of encrypted files to meaningless gibberish or misleading names and still are able to obtain the original identity of the file at any time - if you know the Access Key. By the same method you can at any time make a check whether your archive file is still uncorrupted, in the physical sense. you can free download FileHashler 0.1.0 now.
