1 Symmetric-key (Secret-key)
2 Asymmetric- key (Public-key)
1 Symmetric-key : - In symmetric-key cryptography, the same key is used by the sender (for encryption) and the receiver (for decryption). The key is shared.
2 Asymmetric-key : - Asymmetric cryptography, also known as public key
cryptography, uses public and private keys to encrypt and decrypt data. The keys
are simply large numbers that have been paired together but are not identical
(asymmetric).
↪ Comparison between two categories of cryptography
⇾ What is Encryption : - Data encryption translates data into another form, or code,
so that only people with access to a secret key (formally called a decryption
key) or password can read it. Encrypted data is commonly referred to as
ciphertext, while unencrypted data is called plaintext.
⇾ What is Decryption : - Decryption is the process of taking encoded or encrypted
text or other data and converting it back into text that you or the computer
can read and understand. This term could be used to describe a method of
un-encrypting the data manually or with un-encrypting the data using the proper
codes or keys.
