Public Key Encryption, also known as asymmetric encryption, is a widely used method for data encryption today. Public Key Encryption is also referred to as asymmetric encryption!
1. Understanding Public Key Encryption
Public Key Encryption, also known as asymmetric encryption, is a method of encrypting data using two distinct keys: the Public Key (available for user use) and the Private Key. Data encrypted with the public key can only be decrypted with the private key, and vice versa. Public Key Encryption, or asymmetric encryption, is widely used for TLS/SSL.
Public Key Encryption is also referred to as asymmetric encryption and is extensively employed for TLS/SSL.
2. Key Features of Public Key Encryption
Key Highlights of Public Key Encryption
- Public Key Encryption is crucial as users can only decrypt data that has been encrypted if they possess the private key.
- One of the two keys, either the public or private key, can be used for encryption, with the other used for decryption.
- In a public key encryption system, public keys can be freely shared for users to encrypt data and verify digital signatures. Only users owning the private key can decrypt encrypted data and create digital signatures.
- The most widely used public key encryption system is RSA (Rivest-Shamir-Adleman).
3. What Does Public Key Encryption Include?
The components of Public Key Encryption include:
- Plain Text (pure text): data we can read and understand. This data is used as input for the encryption algorithm.
- Cipher Text (encrypted data): data that has been encrypted, the output result of the encryption algorithm. Because the data is encrypted, we cannot comprehend this data.
4. Weaknesses of Public Key Encryption
- Public key encryption, or public key cryptography, is susceptible to being 'cracked' by Brute-force attacks.
- In case of losing the private key, it is considered an encryption failure.
- Additionally, public key encryption is vulnerable to Man-in-The-Middle Attacks. If an attack occurs, a third party can crack the public key and manipulate these keys.
