18Dec1998: Added sunlink.c and references to mcrypt.c. Now the -u
           flag can be used to delete (secure delete) the input file.

17Dec1998: Added mcrypt.1. At last a manpage!

12Jan1999: Minor changes in sunlink.c (prints a warning when more than one hard links
           for a file exist)

12Jan1999: Added unix crypt compability.
           DES 7bit mode is now working.

13Jan1999: Major version update 2.1.0
           Added libmcrypt.a (lcrypt.c)
           DES, 3DES, Blowfish, 3-WAY and GOST are implemented there.
           Code cleared in mcrypt.c
           Proper header files were created (at last!)
           Because of these changes GOST, 3-WAY and DES (and tripleDES) are 
           not compatible with previous versions of this program. 

15Jan1999: version 2.1.1
            Makefile in ufc-crypt is now added into the main configure script.
            Algorithm information are now stored into encrypted files, so
            that version is also incompatible with previous ones if the
            --bare flag is not specified.
            NLS support is added. Greek language support.
16Jan1999: crc32.c: Added. CRC32 check added.

17Jan1999: mcrypt.c: The number of bytes of plaintext of the last block is now
            represented in one byte (previously 4). So that version is not
            compatible with previous ones. Minor changes to use fread and
            fwrite instead of read and write (much faster).
           mcrypt.c: The crc32 is now stored encrypted in the file.
17Jan1999:  blowfish.c: The algorithm changed according to the "new" blowfish.

20Jan1999: version 2.1.3
           mcrypt.c: Many bugfixes. When specifying many files and one key
            via --key the key length was reduced for every file. Fixed.
           mcrypt.c: signal handling.
            functions.c: Added this file to make bzero() and signal() work in
            POSIX systems that use memset() and sigaction().
           mcrypt.c: Output files are now deleted if encryption/decryption
            fails. (The same if we get a signal)
           defines.h: Checks were added to find 32bit, 16bit and 8bit
            integers. (using defines in configure.in)

21Jan1999: mcrypt.c: -e flag was removed (it was optional)
            -t --type parameter was replaced by -a --algorithm parameter.
           locks.c: Added. Now locking is performed to input (read) and 
            output (write) files via fcntl.

29Jan1999: cast.c: Added CAST-128. Adopted from the lsh project.
           Originally written by Steve Reid <sreid@sea-to-sky.net>
           lcrypt.c: The library is now more functional. It supports
           multithreading.

29Jan1999: lcrypt.c: An error was found in the key handling. Corrected.
