Cryptography uses algorithms to transform data into unreadable ciphers for security. Symmetric encryption uses a single password for encryption and decryption, while asymmetric encryption uses two keys. Asymmetric encryption is considered more secure because the key that triggers decryption is not shared. Passphrases should be unique and alphanumeric to improve security. Cryptography is a form […]
Encryption methods include hashing, symmetric encryption, and asymmetric encryption. Hashing creates a unique signature for a message, while symmetric encryption uses a private key to encrypt and decrypt data. Asymmetric encryption uses two keys for added security. All methods protect confidentiality, detect tampering, and verify identity. There are three basic encryption methods: hashing, symmetric encryption, […]
AES is a powerful symmetric key encryption technique used to secure electronic data such as operating systems, hard drives, and emails. It was commissioned by the US government and is widely used by governments and security companies worldwide. AES encryption works by repeatedly transforming plaintext into ciphertext and back again. It uses a fixed 128-bit […]
Encryption is a method of keeping data secure and private. Rijndael encryption, developed by Belgian cryptographers, is a block cipher with keys of 128, 192, and 256 bits. It was selected as the new standard in 2000 and is used in AES, which is adopted by several organizations for important data transfers. Attempts to crack […]
Email encryption software, such as PGP, S/MIME, and TLS, converts email text into an encrypted format to prevent unauthorized access. TLS is a protocol that prevents email address spoofing and uses cryptographic hashing algorithms for authentication and encryption. S/MIME uses certification keys for encryption and decryption and supports centralized key management. PGP includes digital signatures […]
