Detailed explanation-1: -File encryption helps protect your data by encrypting it. Only someone with the right encryption key (such as a password) can decrypt it.
Detailed explanation-2: -Open PGP encryption is used for encrypting, decrypting, and authenticating files. It uses hashing, data compression, symmetric private-key cryptography, and asymmetric public-key cryptography to keep data secure.
Detailed explanation-3: -The Advanced Encryption Standard (AES)-established as the US government standard for encryption. AES is a symmetric-key algorithm that uses block cipher methods. It is available in 128, 192, and 256bit sizes, using an increasing number of rounds of encryption according to size.
Detailed explanation-4: -How encryption works. Encryption works by encoding “plaintext” into “ciphertext, ‘’ typically through the use of cryptographic mathematical models known as algorithms. To decode the data back to plaintext requires the use of a decryption key, a string of numbers or a password also created by an algorithm.
