  • Sha-256 not correct? what format is required for login?

    hey guys i've had this issue for a while but i'm coming closer to solving the issue.

    what i m trying to do is i am trying to convert a string to sha-256 which i can do but the string that my java code is not the same as what i get from linux

    linux:
    echo adam | sha256sum
    sum: f3fd8f664c016fec4372773c6b6ac06d0789857297b2473bcd 33fba523dad5fc

    java:
    Code:
    MessageDigest md = MessageDigest.getInstance("SHA-256");
    	byte[] hash = md.digest(consumer.getConsumerPassword().getBytes());
    
    	StringBuffer sb = new StringBuffer();
    	for(byte b : hash) {
    	    sb.append(String.format("%02x", b));
    	}
    sum: f7f376a1fcd0d0e11a10ed1b6577c99784d3a6bbe669b1d13f ae43eb64634f6e


    the two sum's are similar but i don't understand why???

    also what should spring security be expecting as far as format for sha-256 if i have this in the spring security file?
    Code:
    	<authentication-manager alias="authenticationManager">
    		<!-- DAO Based Security -->
    		<authentication-provider>
    			<password-encoder hash="sha-256" />
    			<jdbc-user-service data-source-ref="dataSource"
    				users-by-username-query="SELECT A.username AS username, A.password AS password, A.enabled AS enabled FROM admin A where A.username=?"
    				authorities-by-username-query="SELECT A.username as username, A.password as password, R.name as authority FROM admin A left join admin_roles AR on A.id=AR.admin left join roles R on AR.roles = A.id WHERE A.username=?" />
    		</authentication-provider>
    	</authentication-manager>
