HarmonyOS 鸿蒙Next RSA签名

public static String sign(Map< String, Object > params) {
try {
PKCS8EncodedKeySpecpriPKCS8 = new PKCS8EncodedKeySpec(Base64.decode(privateKey, Base64.DEFAULT));
KeyFactorykeyf = KeyFactory.getInstance(“RSA”);
PrivateKeypriKey = keyf.generatePrivate(priPKCS8);
java.security.Signaturesignature = java.security.Signature.getInstance(SIGN_RSA2_ALGORITHMS);
signature.initSign(priKey);
signature.update(getSignCheckContent(params).getBytes(“utf-8”));
byte[] signed = signature.sign();
return Base64.encodeToString(signed, Base64.DEFAULT);
} catch (Exception e) {
throw new RuntimeException(“RSAcontent”, e);
}
}

2.鸿蒙端代码如下，签名成功，但是服务器端不能通过

export function signMessagePromise(params: Map<string, string>, key: string): Promise<string> {
return new Promise((resolve, reject) => {
let data = getSignCheckContent(params)
let dataArray: cryptoFramework.DataBlob = { data: new Uint8Array(buffer.from(data, ‘utf-8’).buffer) };
let keyArray: cryptoFramework.DataBlob = { data: Base64Util.decodeSync(key) };
let rsaGenerator = cryptoFramework.createAsyKeyGenerator(“RSA1024|PRIMES_2”);
let signer = cryptoFramework.createSign(“RSA1024|PKCS1|SHA1”)
let keyGenPromise = rsaGenerator.generateKeyPair();
keyGenPromise.then(keyPair => {
let globalKeyPair = keyPair;
let priKey = globalKeyPair.priKey;
return signer.init(priKey);
})
.then(() => {
return signer.update(keyArray);
})
.then(() => {
return signer.sign(dataArray);
})
.then((dataBlob: cryptoFramework.DataBlob) => {
// return dataBlob.data.toLocaleString() 
let result = dataBlob.data.toLocaleString();
resolve(result)
})
.catch((error: BusinessError) => {
Logger.debug(“error”, JSON.stringify(error))
reject(error)
});
});
}
