我希望将一些Java代码转换为C#。
Java代码:
private static final byte[] SALT = "NJui8*&N823bVvy03^4N".getBytes();
public static final String getSHA256Hash(String secret)
{
try {
MessageDigest digest = MessageDigest.getInstance("SHA-256");
digest.update(secret.getBytes());
byte[] hash = digest.digest(SALT);
StringBuffer hexString = new StringBuffer();
for (int i = 0; i < hash.length; i++) {
hexString.append(Integer.toHexString(0xFF & hash[i]));
}
return hexString.toString();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
throw new RuntimeException("SHA-256 realization algorithm not found in JDK!");
}
当我尝试使用SimpleHash类时,我得到了不同的哈希值。
更新:
例如:
Java:byte[] hash = digest.digest(SALT); 生成的哈希值(前6个字节)为:
[0] = 9
[1] = -95
[2] = -68
[3] = 64
[4] = -11
[5] = 53
....
C#代码(SimpleHash类): string hashValue = Convert.ToBase64String(hashWithSaltBytes); hashWithSaltBytes的前6个字节为:
[0] 175 byte
[1] 209 byte
[2] 120 byte
[3] 74 byte
[4] 74 byte
[5] 227 byte
