Sha 係單向 rsa 係雙向,驟眼睇落好似sha secure 啲,但其實係咪用法唔同無得咁比?![]()
Rsa is asymmetric encryption and SHA is hash function.
兩樣唔同用法
yes, 仲有symmetric (DES, 3DES, AES) 同aymmetric algorithm (RSA, elliptic curve) 嚟做 encryption. PKI 就加埋digitial signature, hashing, 同 encryption
Yup
Generally,Two encryption methods are working tougher,
Hash function is used to generate message digit only....
