        builder.append(String.format("%02x", b));
    }
    String stringFormatMethod = builder.toString();
    Assert.assertEquals(AuthUtils.makeDigestPayload(mockConfig, "user-pass-section"), sha);
    Assert.assertEquals(sha, stringFormatMethod);
}

Example 19 with MessageDigest

use of java.security.MessageDigest in project tomcat by apache.

the class ConcurrentMessageDigest method init.

/**
