Public key cryptography uses two keys to encrypt and decrypt data, with one key being public and the other private. This method is more secure than symmetric encryption, as it doesn’t require a shared secret key. PGP is a popular program for public key encryption, which can also be used for digital signatures and secure […]
Public key cryptography uses a pair of keys, one public and one private, to encrypt and decrypt data. The public key can be shared, while the private key must be kept secret. The system is mathematically secure and commonly used in applications like email encryption. Public key cryptography is a widely adopted cryptographic system used […]
Quantum cryptography uses quantum mechanics to generate a private and secure key for encryption. It involves the transmission of polarized photons that are received and decoded using corresponding filters. The exchange of information to generate a shared key can detect eavesdropping and generate a new key if necessary. Once a key is generated, an encryption […]
Asymmetric key cryptography uses a public key to encrypt text, which can only be decrypted by a private key. It allows secure communication without sharing secret information, but is slower and can potentially be cracked. It is the basis for tools like PGP, SSL, and TLS, and can guarantee confidentiality and authenticity. The strength of […]
