I'm using the following Android code to generate a HmacMD5 hash. When I generate the hash from the Android App I get the following: J0t��j#߸� bq- �. When I generate the hash from a .net console application I get: SjB0j+xqI9+4hxticS0Cjw==. Notice the difference and that the Android has has special chars in it. Is this a character set issue?
Aaron ============================================================== Here's the Android code: public class HMACMD5 { private final String HMAC_MD5_NAME = "HmacMD5"; private SecretKeySpec sk; private Mac mac; public HMACMD5(byte[] key) throws GeneralSecurityException { init(key); } public HMACMD5(String key) throws GeneralSecurityException { init(EncodingUtils.getAsciiBytes(key)); } private void init(byte[] key) throws GeneralSecurityException { sk = new SecretKeySpec(key, HMAC_MD5_NAME); mac = Mac.getInstance(HMAC_MD5_NAME); mac.init(sk); } public byte[] ComputeHash(byte[] data) { return mac.doFinal(data); } public byte[] ComputeHash(String data) { return ComputeHash(EncodingUtils.getAsciiBytes(data)); } } public String encodeText(String sKey, String sSrc) throws Exception { HMACMD5 hmacMD5 = new HMACMD5(sKey); byte[] textBytes = EncodingUtils.getBytes(sSrc, "UTF-8"); byte[] encodedTextBytes = hmacMD5.ComputeHash(textBytes); String sEncodedText = EncodingUtils.getString(encodedTextBytes, "BASE64"); return sEncodedText; } ============================================================== Here's the .NET code: public static string EncodeText(byte[] key, string sText, Encoding encoding) { HMACMD5 hmacMD5 = new HMACMD5(key); byte[] textBytes = encoding.GetBytes(sText); byte[] encodedTextBytes = hmacMD5.ComputeHash(textBytes); string sEncodedText = Convert.ToBase64String(encodedTextBytes); return sEncodedText; } -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
