imgp is a command line image resizer and rotator for JPEG and PNG images. If you have tons of images you want to resize adaptively to a screen resolution or rotate by an angle using a single command, imgp is the utility for you. It can save a lot on storage too. Powered by multiprocessing, an intelligent adaptive algorithm, recursive operations, shell completion scripts, EXIF preservation (and more), imgp is a very flexible utility with well-documented easy to use options. ...

This software provides a mean for users to encrypt and decrypt data in the form of text and images. The program follows a basic encryption algorithm that relies on mathematical properties of matrices, such as row operations, matrix multiplication, and invertible matrices . This program works by allowing the user to input a key in the form of a matrix, on which the program bases the encryption. The program then performs the encryption. The software only works in the scope of text files with a maximum of 150 characters, and image files with a maximum size of 128 x 128.

A library written in Visual C# for encrypting a text message into an image file, and decrypting an image file to get the text message using Rijndael Algorithm, RSA Algorithm, and LSB Substitution Algorithm.

...The purpose of the project is to capture and address unintentional human errors that could be resolved at the client side during the login process. Solution Abstract: An array of images are loaded at the client side. One of the images is displayed for every password entered based on a simple algorithm. The image is computed based on the password and hence it will change only when the user changes his password. Hence, the displayed image will become familiar to the user until he changes the password. It helps the user understand whether he input the right password before sending it to the server. This would be of great help in highly busy servers like stock-market and bandwidth challenged networks such as mobile data networks and dial-up networks.
