What is Data Encryption

Encryption is a security method in which information is encoded in such a way that only authorized user can read it. User who has it's decryption keys, files will have the authority to read it.

Encrypted data is commonly referred to as ciphertext, while unencrypted data is called plaintext. In the other words, we can say that encrypted data resides in ciphertext format and making the data encrypted.

Encryption is a process of conversion of data from a readable format into an encoded format that can only be read or processed after it's been decrypted.

Types of Encryption

There are two main types of data encryption exist - asymmetric encryption, also known as public-key encryption, and symmetric encryption.

1. Symmetric Key encryption

Symmetric key encryption algorithm uses same cryptographic keys for both encryption and decryption of cipher text.

2. Public Key encryption

Public key encryption algorithm uses pair of keys, one of which is a secret key and one of which is public. These two keys are mathematically linked with each other.

Conclusion

What is Data Encryption? Encrypted data can only be read or processed after it has been decrypted, using a decryption key or password. Only the sender and the recipient of the data should have access to the decryption key.
