It can't (other than using something like a perl expression).
However you can match a string that happens to be the result of a
base64 encoding of the required source string. If the string may be
at a variable offset within the base 64 encoding, you may need
multiple sections within the pattern to match the different byte
offsets (probably up to a total of 8 variants).
