/** Prefix for hashing functions.
|
|
|
|
These prefixes are inserted before the source material used to
|
|
generate various hashes. This is done to put each hash in its own
|
|
"space." This way, two different types of objects with the
|
|
same binary data will produce different hashes.
|
|
|
|
Each prefix is a 4-byte value with the last byte set to zero
|
|
and the first three bytes formed from the ASCII equivalent of
|
|
some arbitrary string. For example "TXN".
|
|
|
|
@note Hash prefixes are part of the Ripple protocol.
