Elementary inhomogeneous inequality for three non-negative reals. Mind sharing your opinions on how to proceed next? Almost the same as higuaro solutions but with a lot of fixes to make it work, the following code tested and working since higuaro not working well like characters went into numbers and when you reverse its get single number and damage everything: You can encode the ip String to base64, reverse the string, and then use a Caesar cipher: This is simplest encrypt/decrypt code but it is not secure. Vigenere Cipher is a polyalphabetic substitution technique that is used for encrypting and decrypting a message text.

While looking for such solution I came across this simple Blowfish implementation, which is very easy to understand and implement. From the wikipedia link: As with all single-alphabet substitution ciphers, the Caesar cipher is easily broken and in modern practice offers essentially no communication security. I will follow all of them.I Have Create My Own Website Plz Visit Related to encrypt text . I want my program to create a random one-word string based on this IP address which can be easily decrypted without a key or password or additional security.
