[Prototype]Encryption is basically used to spoof your original data so that it can be read by only the person its intended for. So obvious reason for encryption is to make your data transmission secure. For eg. Military transmission. This is a highly classified data which should not be intercepted by the others.
There are various encryption techniques like,
- Advance Encryption Standard (like Rijndale & few others come under AES. This is used by military).
- Private key encryption [This is a category of encryption]
- Public key encryption [This is a category of encryption]
- Blowfish
- Twofish
- RSA
- SHA
- Message Digest (v 1,2,3,4,5). Currently MD5 is very famous.
... and the list is very big.
Make sure that encrypting and encoding are two different things. Encoding is done to maintain the reliability of data and to detect errors easily. Encoding is not meant for security. -
