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

[adam2510]

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:

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?
