mam's Issues

Mam bindings broken (regression)

combine mask and hmac into one

Reduce the number of hash iterations required to create a message by using the same curl instance to mask and to hash the message.

It should duplex mask the following in sequence:

The pascal-style length of the trytes
The message (prepended with the next channel key)
It should then compute the nonce given the curl instance (and mask it)
the signature from the above authenticated cipher (hmac) and sibling hashes

make the signature sign the encrypted ciphertext hmac

Could not compile `iota-trytes`

I git cloned the repo then ran cargo build --all --release which returned the error Could not compile iota-trytes`. I am have not used cargo before so is this an issue with my system or an issue with iota-trytes?

Here is every command I used start to finish:

make tryte-encoded length to represent the number 0

digest key behind iota.rs latest

Update it for the method signature, and copy curl rate to signature at the end.

merkle root doesn't parse for tree length of 1

string length needs to be able to represent 0

MAM for python3

will Pyota come with MAM in the future and can we be able to use it separately if we want?

Note the end of a tree

When parsing a message, it would be useful to return whether it used the last key in the tree, so that the user knows to not look in that tree any longer.

This can be known if the hash is always last when calculating the root.

Steps to compile a native static library for deep embedded devices

The instructions to compile MAM in native form as static library are unclear which inhibits the MAM to be used with sensor nodes to encode messages to be inserted on Tangle.

Encoded message length should only include the length of the actual message

Since the next merkle tree root is of fixed size 243 trits, there is no need to encode this in the message length, the program should infer it.

separate tree generation from mam creation

message_key does not return Result<usize, MamError>, key uses slice of vecs

Note: The key should be root + index.

Javascript build

Hi,
I am trying to build the Javascript lib. Following the direction in the readme, I get an error:

In case the asmjs-unknown-emscriptenw is a typo, I also tried this, which looked more successful, but there are no javascript files anywhere:
