Given some input text (set a maximum):
base64encode(encrypt(plainText))
and
decrypt(base64decode(encText))

Switch from CBC to CTR or GCM mode

Add an hash table to prevent re-computation of the hashes for the same file

• remove the global defined structure and update all the code
• use swapped with g_signal_connect

Not a 1:1 port of the GUI, but stripped down version with some basic features like hash and file enc.

Currently, only one file at a time can be encrypted/decrypted.

• add gmenu support (About and Exit)
• add software icon

Quit button can be clicked if and only if all the threads have ended their computation.

Support for multiple file selection and encryption/decryption

• asymmetric encryption (RSA or ECC or both?)
• review algo options (for example GCRY_CIPHER_SECURE)

Possibility to choose between single or double encryption (if double is choosed a different password [and maybe cipher algo] must be used)

At the actual state there is a poor error handling. This must be improved

Error handling must be improved

Counter mode is not recommended for use with block ciphers that have a block size of less than 128-bits (CAST5 and Blowfish have 64 bits).

Which, in case of CAST5 and Blowfish, is 8 and not 16.

Using libnettle support for sha3-256 and sha3-512 will be added to the 2.1.0 release

When encrypting and decrypting a file, a progress bar should be added to improve the user experience.

would be nice to have the possibility to encrypt and decrypt, for example, an external USB drive.

• support data compression using zlib

• remove rmd160
• add GOST R 34.11-94
• add STRIBOG512

• use ui files
• general cleanup (codebase is kinda old)

Choose between crypt/decrypt or compute hashes of written text

When an error occurs, the program should display an info dialog

Each hash must be computed on a new thread

Add an option that allow someone to choose between "crypt" and "hash" functions. If "hash" is given then the type must be supplied (sha, md, tiger, etc)

• error should be reported with a dialog
• if an error occurs, the program should not always exit

When the program is using the maximum number of allowed threads, it's not possible to 're-activate' an already computed hash.
Because this is not a compute-intensive task, it should be allowed.

Should all the hashes be automatically computed or should the user be able to choose which one to compute?

The progress bar when encrypting and decrypting is not the best solution.
An info dialog instead of a progress bar is a better choice, imho.

With slow PCs the gui related to hash computation freeze when selecting complex hash like sha512 or whirlpool. A good solution is to provide a multi-threaded computation.

Make software translatable (using gettext)

add progress bar during enc/dec processes

Support for RMD160, MD5, TIGER, TIGER1, TIGER2, SHA-1, SHA224, SHA256, SHA384, SHA512, WHIRLPOOL
