Simple Encryption and Decryption Tool

Text Encrypted: Key:

Encryption is the process of transforming text to make it unreadable by those without a key or password. This ensures that only those who are supposed to know the contents will be able to see them as they are transformed.

The use of encryption and decryption systems has been around for centuries to protect data and information. These systems vary in complexity and can be used for several different purposes.

The encryption of data is a way to protect the information from unintended recipients. Data can be encrypted using symmetric-key algorithms or asymmetric-key algorithms. Symmetric key algorithms are faster than asymmetric key algorithms, but they require that each party who wants to exchange encrypted messages know the secret key in advance. Asymmetric key algorithms allow for two parties who do not trust one another to communicate securely but are slower due to the mathematical operations involved.
