node aes加解密与Java不一致,以及遇到解密乱码处理方式

如题,java使用的key是经过SHA1PRNG加密的

对应的node版本的代码为

const crypto=require('crypto')
const keyStr=''
const iv=''
let inputEncoding = 'utf8';
let outputEncoding = 'base64';
let algorithm = 'aes-128-ecb';
function getKey(key) {
    let keySha1=crypto.createHash('sha1').update(key).digest('buffer');
    let realKey=crypto.createHash('sha1').update(keySha1).digest('hex').substring(0,32);
    return Buffer.from(realKey,'hex');
}
function encrypt(data,key,iv) {
    key=getKey(key);
    let result=encryptAesData(key,iv,data)
    return result
}
function decrypt(data,key,iv) {
    key=getKey(key);
    let result=decryptAesData(key,iv,data)
    return result
}

function encryptAesData(key,iv,data) {
    const cipher=crypto.createCipheriv('aes-128-ecb',key,iv);
    let crypted=cipher.update(data,inputEncoding,outputEncoding);
    crypted+=cipher.final(outputEncoding)
    // crypted=Buffer.from(crypted,'binary').toString('base64')
    return crypted
}
function decryptAesData(key,iv,crypted) {
     crypted=Buffer.from(crypted,'base64').toString('binary')
     const decipher=crypto.createCipheriv('aes-128-ecb',key,iv)
     let decoded=decipher.update(crypted,outputEncoding,inputEncoding)
     decoded+=decipher.final(inputEncoding)
     return decoded
   
}

但是呢这个代码解密会遇到乱码的问题
所以应该用这份

const crypto=require('crypto')
const keyStr=''
const iv=''
let inputEncoding = 'utf8';
let outputEncoding = 'base64';
let algorithm = 'aes-128-ecb';
function getKey(key) {
    let keySha1=crypto.createHash('sha1').update(key).digest('buffer');
    let realKey=crypto.createHash('sha1').update(keySha1).digest('hex').substring(0,32);
    return Buffer.from(realKey,'hex');
}
function encrypt(data,key,iv) {
    key=getKey(key);
    let result=encryptAesData(key,iv,data)
    return result
}
function decrypt(data,key,iv) {
    key=getKey(key);
    let result=decryptAesData(key,iv,data)
    return result
}

function encryptAesData(key,iv,data) {
    const cipher=crypto.createCipheriv('aes-128-ecb',key,iv);
    let crypted=cipher.update(data,inputEncoding,outputEncoding);
    crypted+=cipher.final(outputEncoding)
    // crypted=Buffer.from(crypted,'binary').toString('base64')
    return crypted
}
function decryptAesData(key,iv,crypted) {
    // crypted=Buffer.from(crypted,'base64').toString('binary')
    // const decipher=crypto.createCipheriv('aes-128-ecb',key,iv)
    // let decoded=decipher.update(crypted,outputEncoding,inputEncoding)
    // decoded+=decipher.final(inputEncoding)
    // return decoded
    let decip = crypto.createDecipheriv(algorithm, key, iv);

    let data = decip.update(crypted,outputEncoding,inputEncoding) + decip.final(inputEncoding);
    return data
}
