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....
