how can i develope RSA encryption algoritm?

You can obtain existing RSA algorithms and modify them to make a different version, if you want to from scratch, good luck.  Find the requirements for the RSA algorithm and code it.  \n\nlook at this for insight\nhttp://www.di-mgt.com.au/rsa_alg.html\n\nIf the math or logic is too difficult - start small, with ceasar cipher's and work your way up.\n\nThis helped me http://www.cacr.math.uwaterloo.ca/hac/ and this is also an awesome book\nApplied Cryptography: Protocols, Algorithms, and Source Code in C\nby Bruce Schneier (must have for any interested in cryptography)

The traffic on Yahoo Messenger can not be encrypted. You need to buy commercial/industrial grade software for such a need. IBM Lotus SAMETIME is one such example.

Go to Tools, Options, Security to set your password.\nWord passwords are quite weak and easily cracked by readily available tools. You'd be safer encrypting your document with something like WinZip with the AES encryption option or the excellent free PGP.

Why do you need to implement it yourself? Why not use the Crypt::Rijndael_PP module from CPAN?\n\nIf anything, you could use the module as a working implementation to study ( or copy from ).\n\nEDIT: Changed module name.

use System.Security.Cryptography.DESCryptoServiceProvider \nnad other one of same catagory in this for endryption

All in one Secretmaker\n\nGet it at www.download.com\n\nWhy develop one when it's been done for you?

you can find a very good tutorial at the link.\n\nNo need to write whats already writtenm =)

1- Get an SSL Certificate from\nhttp://www.verisign.com\nhttp://www.thwate.com\n2- Install that certificate on your webserver, IIS, or Apache\n3- Create a page that contains a form, and that form should be submitted to a script through https://yourservername/scriptname\n4- Server will automatically send the public key of SSL certificate, your form data will be encrypted using that key, and will be posted to script.\n5- Webserver automatically decrypt that encrypted form data and provide that to the script.

You first need to locate a copy-protect decryption program.  These are not sold in a store.

go to hotscripts.com.. Bunch of good code out there. I generally edit code with a regular editor then upload with SSH/SFTP

sure. \n\nI am 27 and i do it as a hobby in my white hat work for \nMINTM purposes.\n\nbut I am not a think tank. so what kind of stuff are you looking for exactly.\n\nIn general first start is math. study the history of how simple encryption started. move on to enigma cause that's when stuff picks up, then a blend of steganography would surley excite you. \n\nas for actual decryption and or how to create a new algorithem, I recommend studying permutational algorithims with Mue and Limbda, that's always a good start.\n\nhope that's usefule. \n\ngoogle up the stuff you don't understand.\n\n8t3 i make m1st4k3s 0n purpos3 ;-)\n\nregards,\n\nCysmn

you can run programs on them, you can write programs, encryption is an algorithm.. so .. you could run an encryption program to encrypt your data or to recall it with a password maybe... but...why would you WANT to encrypt stuff on a graphing calculator?

SSL is the current standard for data encryption on the Internet.  Encryption will not solve the problem alone and good application design and business practices will help as well.\n\nIf you're just starting off I'd outsource the problem to a reputable contracting firm.

Symmetric encryption:\n\n1)Speed is fast\n2)Size of cipher text is usually the same or less than that of the plain text\n3)Number of keys used is the square of the number of participants.\n4) Key exchange is a major problem (hence, algorithms like the Diffie-Hellman Key Exchange algorithm are used)\n5) More storage space required\n\nAsymmetric encryption\n\n1) Slower in speed\n2) Cipher text size is usually greater than that of the plain text\n3) Number of keys used is same as the number of participants.\n4) Key exchange is no problem \n5) Less storage space required\n\nHope that helps u..

You don't encrypt data with MD5, you create a hash that corresponds to that data and can be verified by calculating it again. It helps prove a certain message has not been altered. No good for encrypting by itself.
