【踩坑】Dart 的 RSA 加解密报错

2023-08-03 2023-08-06

Dart 的 RSA 加解密报错：Unhandled Exception: type 'ASN1Sequence' is not a subtype of type 'ASN1Integer' in type cast

  • Dart 中的 RSA 密钥中没有 RSA 关键字，而 Go 语言生成的 RSA 密钥中包含 RSA 关键字
  • 将 RSA 关键字从 RSA 密钥中去除

转换公钥中的 RSA 关键字

  • 将 -----BEGIN RSA PUBLIC KEY----- 转换为 -----BEGIN PUBLIC KEY-----
  • 将 -----END RSA PUBLIC KEY----- 转换为 -----END PUBLIC KEY-----
rsaPublicKey = rsaPublicKey.replaceAll("-----BEGIN RSA PUBLIC KEY-----", "-----BEGIN PUBLIC KEY-----");
rsaPublicKey = rsaPublicKey.replaceAll("-----END RSA PUBLIC KEY-----", "-----END PUBLIC KEY-----");

转换私钥中的 RSA 关键字

  • 将 -----BEGIN RSA PRIVATE KEY----- 转换为 -----BEGIN PRIVATE KEY-----
  • 将 -----END RSA PRIVATE KEY----- 转换为 -----END PRIVATE KEY-----
