RemoteFile.hash specification

[fathzer]

Hello,

com.pcloud.sdk.RemoteFile.hash() returns the hash of the file content.
I hoped to use it to detect differences between pcloud hosted and local files without the cost of an extra call to ApiClient.getChecksums(int).

Unfortunately, I found nowhere a specification of this hash (It does not seem to be SHA1, MD5 or others classical hashes).
Could it be possible to have it documented?
