Question

如题：HarmonyOS cryptoFramework如何生成64位字符的sm2公私钥？

Answer 1

参考示例：

let keypairGenerator = cryptoFramework.createAsyKeyGenerator("SM2_256")
let key = keypairGenerator.generateKeyPairSync();
let x = key.pubKey.getAsyKeySpec(cryptoFramework.AsyKeySpecItem.ECC_PK_X_BN);
let y = key.pubKey.getAsyKeySpec(cryptoFramework.AsyKeySpecItem.ECC_PK_Y_BN);
let puk = x.toString(16) + y.toString(16)
console.log("sm2Key===>" + puk);
let prk = key.priKey.getAsyKeySpec(cryptoFramework.AsyKeySpecItem.ECC_SK_BN);
console.log("sm2Key===>" + prk.toString(16));
