You should ensure that all hex digit strings follow the same rule.
Are SHA-1 object names case insensitive too?

Case insensitivity has a history of being awkward. SMTP has always had
case-insensitive commands, though the RFCs have always written them in
upper case and implementations have pretty much all emitted them in upper
case. See http://tools.ietf.org/html/rfc5321#section-2.4 especially the
caveat about broken case-sensitive implementations.
