keyStore rsa privateKeyEntry, public 密钥和私钥相等

Question

我生成了 RSA 密钥并将其存储到 android keyStore 中，然后我生成了一个 AES 密钥并使用 RSA public-key 对其进行加密，当我想解密加密的 AES-key 时出现此错误：java.security.InvalidKeyException: Need RSA private or public key

    KeyStore.PrivateKeyEntry privateKeyEntry = (KeyStore.PrivateKeyEntry) keyStore.getEntry(KEY_ALIAS, null);
    Cipher output = Cipher.getInstance(RSA_MODE, "AndroidOpenSSL");
    output.init(Cipher.DECRYPT_MODE, privateKeyEntry.getPrivateKey());

日志后 privateKeyEntry.getCertificate().getPublicKey() 和 privateKeyEntry.getPrivateKey()

我看到键 mModulas 是相等的，有人知道吗？

Answer 1

您正在使用由 "AndroidKeyStore" 密钥管理的密钥。尝试在此处删除 "AndroidOpenSSL"

 Cipher output = Cipher.getInstance(RSA_MODE, "AndroidOpenSSL");

after log privateKeyEntry.getCertificate().getPublicKey() and privateKeyEntry.getPrivateKey() I saw the keys mModulas are equals, anyone has any idea about that?

私钥的public模数与public密钥相同。这很正常

keyStore rsa privateKeyEntry, public 密钥和私钥相等

keyStore rsa privateKeyEntry, public key and private key are equals

android

rsa

keystore

public-key

private-key
