Functions

check_length	Check whether a length (as obtained from length(&signing_encoding)) is valid.
check_previous	Check whether the given message has the correct previous entry with respect to the hash of the previous message (or None if it is the first message of the feed).
check_sequence	Check whether the given message has the correct sequence number compared to the previous message's sequence number. If the message is the first of its feed, call this as check_sequence(&msg, 0).
check_signature	Check whether the signature signs the signing encoding by the author.
hash	Compute the hash of the given signing encoding.
hash_and_length	Compute the hash and length of the given signing encoding in one go.
length	Compute the length of the given signing encoding.
