Hello everyone, I have an old Java authentication web service that I
must use in my rails development. The service takes a username and an
encrypted password. I''m having trouble reproducing the same encryption
algorithm.
Here is the Java encryption function:
public static String digest(String text)
{
MessageDigest mDigest = null;
try
{
mDigest = MessageDigest.getInstance("SHA");
mDigest.update(text.toUpperCase().getBytes("UTF-8"));
} catch (NoSuchAlgorithmException nsae) {
nsae.printStackTrace();
} catch (UnsupportedEncodingException uee) {
uee.printStackTrace();
}
byte[] raw = mDigest.digest();
return new BASE64Encoder().encode(raw);
}
Here is the Ruby encryption function:
...
require ''digest/sha1''
Base64.encode64(Digest::SHA1.hexdigest(''ruby''))
...
Now here is the resulting String calling the Java function with the
string ''ruby'':
"oJtN1kHfQdCCLFN7ATWgAxIH6bc="
Here is what I get with my Ruby function for the same string:
"MThlNDBlMTQwMWVlZjY3ZTFhZTY5ZWZhYjA5YWZiNzFmODdmZmI4MQ==\n"
So, anybody knows what I''m doing wrong?

Digest::SHA1.digest(''ruby'') would be the same behaviour as your java code (don''t forget to convert the text to upper case) Fred.

Works. Thank you for your help!
