Use CryptoJS for MD5 and AES Encryption and Decryption of Request Parameters

tip

EchoAPI has built-in CryptoJS (https://github.com/brix/crypto-js), which makes it convenient to perform various encryption and decryption on request parameters.

MD5 Encryption​

CryptoJS.MD5('string to be encrypted').toString()

SHA256 Encryption​

CryptoJS.SHA256('string to be encrypted').toString()

Base64 Encryption​

CryptoJS.enc.Base64.stringify(CryptoJS.enc.Utf8.parse('string to be encrypted'))

Base64 Decryption​

CryptoJS.enc.Base64.parse("string to be decrypted").toString(CryptoJS.enc.Utf8)

Simple AES Encryption​

CryptoJS.AES.encrypt('string to be encrypted', 'secret key').toString()

Simple AES Decryption​

CryptoJS.AES.decrypt('string to be decrypted', 'secret key').toString(CryptoJS.enc.Utf8)

Custom AES Encryption and Decryption Functions​

The above examples are two simple AES encryption and decryption schemes. In most cases, we need to customize more parameters for AES encryption and decryption, such as encryption mode, padding, etc.

const key = CryptoJS.enc.Utf8.parse("secret key");  // Sixteen hexadecimal digits as the key
const iv = CryptoJS.enc.Utf8.parse('initialization vector');   // Sixteen hexadecimal digits as the key offset

// Decryption method
function Decrypt(word) {
    let encryptedHexStr = CryptoJS.enc.Hex.parse(word);
    let srcs = CryptoJS.enc.Base64.stringify(encryptedHexStr);
    let decrypt = CryptoJS.AES.decrypt(srcs, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 });
    let decryptedStr = decrypt.toString(CryptoJS.enc.Utf8);
    return decryptedStr.toString();
}

// Encryption method
function Encrypt(word) {
    let srcs = CryptoJS.enc.Utf8.parse(word);
    let encrypted = CryptoJS.AES.encrypt(srcs, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 });
    return encrypted.ciphertext.toString().toUpperCase();
}

// In the above methods, mode is the encryption mode, and padding is the padding.
