What is EAESCrypt

EAEScrypt is a utility that is designed to protect sensitive data using secure encryption.

It uses the Advanced Encryption Standard (AES) as published by the Federal Information Processing Standards Publications (FIPS PUBS) and issued by the National Institute of Standards and Technology (NIST).

The extended version of AES (EAES) allows to control the algorithm parameters beyond the officially defined values. According to the specification of the Federal Information Processing Standard for AES (FIPS-197), there is a limited set of valid values for these parameters. Values outside this range are not compatible with FIPS-197 specification and should be considered "unofficial".

The official version of AES allows only 128-bit, 192-bit or 256-bit keys, and EAESCrypt is fully compliant with FIPS-197 when using these values. But EAEScrypt can use any key size from 128-bit to 2048-bit. Although larger keys make the algorithm more secure, they also make it slower.

EAESCrypt is a FREE software. Its source code is freely available for inspection and use, under the terms of the GNU Lesser General Public License.

EAESCrypt is a command line utility. The instaler for Windows 7 provides some basic functionality in the context menu for the files in Windows Explorer, to encrypt and decrypt them, as well as to manage the encryption keys.

The source files are NOT hosted in SourceForge because this host is subject to the legislation of the United States, which restricts the use of encryption algorithms.

The Brazilian laws don't restrict the use of cryptographic algorithms. If you do not live in Brazil, refer to the legal notice to see if you are eligible to get EAESCrypt.

The source files, as well as the instalation package, are available at the home page hosted in Brazil

Windows 7 instalation

This version of EAESCrypt comes with a package that allows you to install it on a computer with Windows 7 operating system.

The installer doesn't work for operating systems previous to Windows 7 (e.g. Windows XP). The installer hasn't been tested for the Windows 8 operating system.
