A communication or data file is transformed via encryption so that its contents are obscured from unauthorized readers.
What is meant by Encryption?
- Information is encoded through the process of encryption.
- This technique transforms the information's initial plaintext representation into an alternate version known as ciphertext.
- Only parties with the proper authorization should be able to convert ciphertext to plaintext and gain access to the original data.
- Although encryption does not by itself stop interference, it does hinder a potential interceptor from understanding the material.
- An encryption technique typically employs a pseudo-random encryption key produced by an algorithm for technical reasons.
- Without the key, it is feasible to decrypt the message, but doing so requires a lot of computer power and expertise for a well-designed encryption scheme.
- With the key provided by the sender to recipients but not to unauthorized users, an authorized recipient can quickly decrypt the communication.
- Technically speaking, it is the process of changing plaintext that can be read by humans into ciphertext, which is incomprehensible text.
