How to generate a hash according to GOST (there is a code in JAVA, you need it in php)?

Question

PHP

Good afternoon.
The task is to send files using the PUT method to a specific server, and then transfer the hash of this file via SOAP.
The documentation says that it is required to hash according to the GOST 34.11-94 algorithm.
Tried like this:

$string = file_get_contents($path);
$hash = bin2hex(mhash(MHASH_GOST,$string));

But when sending a SOAP envelope, an error occurs saying that the hash is not correct.
I contacted support, they gave me an example of hashing in java:

byte[] bytes = IOUtils.toByteArray(new FileInputStream("/home/zinin/tmp/xxx.pdf"));
        MessageDigest digest = MessageDigest.getInstance(GostConsts.GOST_DIGEST_ALGORITHM_NAME, CommonConstants.TRUSTED_JAVA_PROVIDER);
        byte[] result = digest.digest(bytes);
        LOGGER.info("hash: " + new String(Hex.encodeHex(result, true)));

I also calculated the hash for the string "somestring" = "5ed5fe405f6872d23fb71ce21321bcb514e1fe59bdd9f21e3bc1d3fe3c48d758";
Calculate the hash in php:

$string = "somestring";
echo bin2hex(mhash(MHASH_GOST,$string));
//Результат:66231654633f311301af1c9eb192e5a7e85f0a2036ce37a1bce7d1c502f009bf
echo hash('gost', $string);
//Такой же результат

Which is not true.
I tried to generate a hash using the rhash utility:

The RHash program supports the calculation of GOST R 34.11-94 with test and CryptoPro parameters and both hash output formats (low bytes first by default). Call examples:
rhash --gost empty-file.txt
rhash --gost --gost-reverse empty-file.txt
rhash --gost-cryptopro empty-file.txt
rhash --gost-cryptopro --gost-reverse empty- file.txt

But I did not get the desired result, although I tried all these examples. By the way, the first option considers the same hash as the given php code.
In general, I do not know which way to dig. Tell me how to implement the above mechanism in java using php?
Thank you!

Answer 1

In php 5.6 should work:
echo hash('gost-crypto', 'somestring');
