我只想使用
Android在<{1}}中加密和解密文字。
我找到了一些示例，但找不到ChaCha20以正确的方式制作它。我想要solution ChaCha。 someOne可以指导我如何实现它。我试着修改这些代码了很多。
SecurityUtil
encryption我尝试将public class SecurityUtil extends Properties {
public String decrypt(String name, String keyString)
throws Exception {
BlowfishEngine engine = new BlowfishEngine();
PaddedBufferedBlockCipher cipher =
new PaddedBufferedBlockCipher(engine);
StringBuffer result = new StringBuffer();
KeyParameter key = new KeyParameter(keyString.getBytes());
cipher.init(false, key);
byte out[] = Base64.decode(name);
byte out2[] = new byte[cipher.getOutputSize(out.length)];
int len2 = cipher.processBytes(out, 0, out.length, out2, 0);
cipher.doFinal(out2, len2);
String s2 = new String(out2);
for (int i = 0; i < s2.length(); i++) {
char c = s2.charAt(i);
if (c != 0) {
result.append(c);
}
}
return result.toString();
}
public String encrypt(String value, String keyString)
throws Exception {
BlowfishEngine engine = new BlowfishEngine();
PaddedBufferedBlockCipher cipher =
new PaddedBufferedBlockCipher(engine);
KeyParameter key = new KeyParameter(keyString.getBytes());
cipher.init(true, key);
byte in[] = value.getBytes();
byte out[] = new byte[cipher.getOutputSize(in.length)];
int len1 = cipher.processBytes(in, 0, in.length, out, 0);
try {
cipher.doFinal(out, len1);
} catch (CryptoException e) {
e.printStackTrace();
throw new Exception(e.getMessage());
}
String s = new String(Base64.encode(out));
return s;
}
}
更改为BlowfishEngine，但它是一个类而不是接口。并尝试了很多方法。
AESWrapper
ChaChaEngine是否有一种简单的方法可以使用chacha简单地加密和解密文本。
