This string looks very much like a Base64-encoded block of 9 bytes. I
really doubt one can deduce more about the nature of the hash (or even if
it actually is a hash and not something else).

In most cases, hashes can only be distinguished by their lengths (e.g. MD5
is 16 bytes long, SHA1 20 bytes, ...). However, if the data consists
of more than just the hash, it might be possible to deduce something
about their nature (e.g. entries in /etc/passwd or /etc/shadow).

If you're pentesting an application, I'd guess you know what kind of
application it is, don't you? If so, can you obtain a copy which you can
experiment with?
