我正在使用加密 API 进行签名并将其发送到使用开放 SSL 验证签名的网络服务器。签名使用 Windows 加密 API 成功验证,但在服务器端使用开放 SSL 验证时出错。
错误:
ECDsa 签名不是有效的 DER 序列
签名功能:
public async sign(data: Uint8Array): Promise<any> {
if (!this.privateKey) {
throw new Error('no private key available for signing');
}
return window.crypto.subtle.sign(
this.getKeyParams(),
this.privateKey,
data,
);
}
private getKeyParams(): EcdsaParams {
return { name: 'ECDSA', hash: coseEllipticCurveNames[ECDSA.ellipticCurveKeys[this.algorithm]] };
}
private async toCOSE(key: CryptoKey): Promise<Map<number, any>> {
const exportedKey = await window.crypto.subtle.exportKey('jwk', key);
const attData = new Map();
attData.set(1, 2); // EC2 key type
attData.set(3, this.algorithm);
attData.set(-1, ECDSA.ellipticCurveKeys[this.algorithm]);
attData.set(-2, base64ToByteArray(exportedKey.x, true));
attData.set(-3, base64ToByteArray(exportedKey.y, true));
return attData;
}
