Public Key Cryptography, also known as asymmetric cryptography, is a cryptographic system that uses a pair of keys for secure communications. A public key, which anyone can know, and a private key, which is kept secret by the owner, are used. The public key encrypts data, while the private key decrypts it, ensuring that only the intended recipient can access the information. It’s also a technical foundation for WebAuthn and passkeys.
Public Key Cryptography provides a robust framework for securing communications by ensuring that only intended recipients can decrypt messages. This method solves the problem of key distribution that plagues symmetric cryptography systems by eliminating the need to securely transmit a shared key.
Offers enhanced security through non-repudiation and the ability to encrypt messages without sharing the encryption key, eliminating key distribution problems.
By encrypting data with a public key and allowing only the holder of the paired private key to decrypt it, ensuring data confidentiality and integrity.
Digital signatures are cryptographic techniques that use the private key to sign data, ensuring authenticity and integrity. They are verified by anyone with access to the signer's public key, crucial for secure online transactions and communications.
Yes, it is often used alongside symmetric cryptography to optimize both security and performance, particularly
