HarmonyOS 鸿蒙Next DSA签名将字符串转化为私钥对象失败 我使用字符串私钥，实现dsa签名的功能，在生成KeyPair的过程中一直失败，报错信息是

message = "convert key fail."
stack = "Cannot get SourceMap info, dump raw stack:

以下是具体代码

static async generateDSAKeyPair(): Promise<cryptoFramework.KeyPair | undefined> {
  try {
    let keyGenAlg = "DSA1024";
    let base64Helper = new util.Base64Helper();
    let key = base64Helper.decodeSync(DSAUtil.DSAKEY)
    let keyUint8Array = new Uint8Array(key); // 调试信息
    let generator = cryptoFramework.createAsyKeyGenerator(keyGenAlg);
    let priKeyBlob: cryptoFramework.DataBlob = { data: keyUint8Array };
    return await generator.convertKey(null, priKeyBlob)
  } catch (error) {
    console.error("生成 DSA 私钥失败:", error);
    return undefined
  }
}

当调用convertKey方法将外来二进制数据转换为算法库非对称密钥对象时，公钥应满足ASN.1语法、X.509规范、DER编码格式，私钥应满足ASN.1语法、PKCS#8规范、DER编码格式。需要确认使用的key信息是否符合，使用如下demo可以正常生成转换，此处keyUint8Array 中的key由asyKeyGeneratorBySpec.generateKeyPair生成，参考https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V14/js-apis-cryptoframework-V14#cryptoframeworkcreateasykeygeneratorbyspec10

针对帖子标题“HarmonyOS 鸿蒙Next DSA签名将字符串转化为私钥对象失败”的问题，以下是专业且直接的回答：

在HarmonyOS鸿蒙Next系统中，若遇到DSA签名过程中将字符串转化为私钥对象失败的情况，通常可能是由于以下原因：

  1. 字符串格式错误：确保提供的私钥字符串符合正确的格式，包括PEM或DER等格式，且未包含非法字符或多余的空格。

  2. 编码问题：私钥字符串可能需要进行Base64解码或其他适当的编码转换，以匹配系统期望的输入格式。

  3. 密钥类型不匹配：检查私钥字符串是否确实为DSA类型的私钥，而非RSA或其他类型。

  4. API使用不当：确保在调用相关API时，正确传递了所有必要的参数，并遵循了API的文档说明。

  5. 权限问题：确保应用程序具有访问和解析私钥的适当权限。

若上述检查均无误，但问题依旧存在，可能是由于系统或库的内部实现问题。此时，建议直接联系鸿蒙系统的官方技术支持团队，以获取更深入的帮助。
