Java Equivalent to PHP's Hmac-Sha1

java equivalent to php's hmac-SHA1

In fact they do agree.

As Hans Doggen already noted PHP outputs the message digest using hexadecimal notation unless you set the raw output parameter to true.

If you want to use the same notation in Java you can use something like

for (byte b : digest) {
    System.out.format("%02x", b);
}
System.out.println();

to format the output accordingly.

hash_hmac analog for Java

Found solution here: java equivalent to php's hmac-SHA1

The problem was in BASE64Encoder. Use

for (byte b : digest) {
    System.out.format("%02x", b);
}
System.out.println();

or

new BigInteger(digest).toString(16);

instead.

HMAC-SHA1: How to do it properly in Java?

On your PHP side, use single-quotes around the key so that the $ character is not treated as a variable reference. i.e.,

hash_hmac("sha1", "helloworld", 'PRIE7$oG2uS-Yf17kEnUEpi5hvW/#AFo')

Otherwise, the key you really get is PRIE7-Yf17kEnUEpi5hvW/#AFo (assuming the variable $oG2uS is not defined).

How to create OAuth HMAC-SHA1 signature on GAE/J?

public String computeHmac(String baseString, String key)
    throws NoSuchAlgorithmException, InvalidKeyException, IllegalStateException, UnsupportedEncodingException
{
    Mac mac = Mac.getInstance("HmacSHA1");
    SecretKeySpec secret = new SecretKeySpec(key.getBytes(), mac.getAlgorithm());
    mac.init(secret);
    byte[] digest = mac.doFinal(baseString.getBytes());
    return Base64.encode(digest);
}

why PHP's hash_hmac('sha256') gives different result than java sha256_HMAC

The output of the php function are lowercase hex digits when the fourth parameter is false. Your second java version however produces uppercase hex digits. Either correct the case difference or you could change the fourth parameter of hash_hmac to true and it will probably match with your first Java version.

ColdFusion equivalent to PHP hash_hmac

I found a solution on this page http://www.isummation.com/blog/calculate-hmac-sha256-digest-using-user-defined-function-in-coldfusion/

Your need to call the function like this

<cfoutput>#LCase(HMAC_SHA256(iv & "." & Encrypted_Data, key))#</cfoutput>

Worked like a charm.

How to generate an HMAC in Java equivalent to a Python example?

HmacSHA1 seems to be the algorithm name you need:

SecretKeySpec keySpec = new SecretKeySpec(
        "qnscAdgRlkIhAUPY44oiexBKtQbGY0orf7OV1I50".getBytes(),
        "HmacSHA1");

Mac mac = Mac.getInstance("HmacSHA1");
mac.init(keySpec);
byte[] result = mac.doFinal("foo".getBytes());

BASE64Encoder encoder = new BASE64Encoder();
System.out.println(encoder.encode(result));

produces:

+3h2gpjf4xcynjCGU5lbdMBwGOc=

Note that I've used sun.misc.BASE64Encoder for a quick implementation here, but you should probably use something that doesn't depend on the Sun JRE. The base64-encoder in Commons Codec would be a better choice, for example.
