Symmetric Encryption :
- Starts with plain readable data ( Plaintext ) and scramble it so it becomes an unreadable ciphertext.
- Encrypting the plaintext to ciphertext will give high-security to your confidential data and only the authorized person who is supported to read this document can read it.
Following are some Encryption terms related to encryption :
Plain text :
Information on its original form. This is known as real text.
Cyphertext :
Information after it has been obfuscated by the encryption algorithm.
Encryption :
The process of changing plaintext into ciphertext.
Decryption :
The process of changing ciphertext into plaintext.
Encryption Algorithm :
Defines how data is transformed when original plaintext data scrambled to
cyphertext.
Encryption Key :
A Key is a secret value, which is used as an input to the algorithm along with the
plaintext data when plaintext is converted into ciphertext.
Cryptography :
Art of concealing information using encryption.
Cryptographer :
An individual who practices cryptography.
Cryptanalysis :
Art of analyzing cryptographic algorithms for identifying the weaknesses.
Cryptanalyst :
An individual who uses cryptoanalysis to identify the weaknesses in the
cryptographic algorithm.
What is a symmetric encryption?
The process of converting readable data unreadable format and converting it back to a readable format using the same key.
Use the same key for encryption and decryption
Plain text is converted to ciphertext using a key at the receiving side, the same
the key is used to convert back the cyphertext to plain text.
