- Data encryption translates the data into another code, so that only people with access to a secret key or password can read it.
- Encrypted data is commonly referred to as cipher text, while not encrypted data is called as plain text.
- Encryption is one of the most popular and effective data security methods used by organizations.
- While transferring the data through a unsafe environment like Internet it is protected by using a algorithm called encryption algorithm.
- During the process they use the key to protect the data from attacks like random trail.
- If the key is lengthy then the data is more protected and the computing is also more.
Example:
- There are mainly two types of data encryption:
- Symmetric encryption and
- Asymmetric encryption.
Symmetric Encryption:
- In symmetric encryption the key used during the encryption and key used during decryption both are same.
- The person who encrypted data send the key to person who decrypting the data after sending the data safely.
Asymmetric key encryption:
- It is a type of encryption where the key during encryption and key used during decryption are different.
- The key used during decryption is called public key and key used during encryption is called private key.
