[JDBC] Unable to store SHA hash
I recently migrated an application from Oracle to Postgresql 7.1. The migration was fairly painless with one exception: User's passwords are hashed using SHA, then stored in the database. Ie. // Get the hash of the password MessageDigest md=null; try { md = MessageDigest.getInstance("sha"); } catch (NoSuchAlgorithmException e) { System.out.println("Error: sha encryption unavailable."); } String hashedPass = new String(md.digest(request.getParameter("pass").getBytes())); This string contains several characters that are outside the normal ASCII range. The string could be stored and retrieved using Oracle and MySQL, but in Postgres any unusual characters become '?'. This corrupts the hash and prevents users from logging on. So far, the following have been tried: - Password stored using PreparedStatement setString() call. Retrieved using ResultSet(). Verified hash corruption in the database. - Password field datatype changed from varchar to bytea. Oddly enough, PreparedStatement.setBytes() can not be used against this datatype. Resorted to using .setString(). Hash was still corrupted at the database level. Any insight into how to accomplish this task would be greatly appreciated.
