Security in Java

From source code,code examples

I figured out how to let my users login with a form rather then using the built in dialog for basic authentication. Only problem is, if they get the username/password wrong, then they will still get that built in dialog.

Security tool that help you perform DES encryption on any file. A separate DES key is generated and that file can only be decrypted using this key. Simple coding help newbies to understand encryption technologies in Java. You can generate your own javadoc API from the source files. Please feedback to my email address to report bugs or comments.

To encrypt and decrypt the all kind of files to prevents unauthorized access by othters people

You Need a password to enter. Supports muiltiple usernames and passwords. Simply easy to add,edit, or remove usernames and passwords. The code is in html form already for easy copy and paste. This code is worthles if you do not have frames if you need help on working with frames email me!!!!

msjsPP is a code snippet that is used to password protect a single html document or a complete section of software. It will limit the amount of invalid guesses allowed, and after X attempts, automatically redirect them elsewhere.

Bring a new idea into javascript protection. Dont blam me this is my first real attempt at programming in javascript.

This code encrypts and decrypts plaintext data. Contains a single-key algorithm with key values that are XORed by the plaintext data. Any feedback, suggestions or rating welcome. ;-)

Scans all ports of a system

Parses the password field and comes back with a percentage of how secure your password is against a hack attempt.

It can lock the folder with your given password so that nobody other than you can access that folder.

The function generates a 160-bit (40-hex-digits representing 20 bytes) message digest for a given message (String) of any length. The digest is unique to the message. It is not possible to recover the message from the digest. The only way to find the source message for a digest is by the brute force hashing of all possible messages and comparison of their digests.

Sidd password 1.0 is a password protect script written in javascript. Its a simple password program, not very useful, you can use it to protect not-so-important things. Uses a .js file for new username and password.

This application is used to encrypt/decrypt text based on a given password, using the Simplified DES algorithm. It produces a different encryption for different passwords, it successfully decrypts text only when the correct password is given.

This program encrypts a message using TRANSPOSITION CIPHER. The program uses a key, provided by the user to encrypt the message. Encrypted message can be decrypted using Transposition Cipher Decryption program, also submitted by me.

This program decrypts a message using TRANSPOSITION CIPHER. The program uses a key, provided by the user to decrypt the cyphertext. Message can be encrypted using Transposition Cipher Encryption program, also submitted by me.

This program let you use Transposition Cipher Encrypt and Transposition Cipher Decrypt from this same program.
