muquit / libsodium-jna Goto Github PK

Hi there
It seems that the message length is not passed when calling sodium().crypto_sign_open.

https://github.com/muquit/libsodium-jna/blob/master/src/main/java/com/muquit/libsodiumjna/SodiumLibrary.java#L312

Whats the reason for this? Passing null will yield in libsodium checking the length itself?

Cheers

Not sure why these wont work (the 2 verify ones also fail with same error). I do already have many of your libsodium-jna functions working normally. I have also implemented a few new ones for you and have recently pushed them to you for merge.

But these ones just seem to fail. (using eclipse neon 64 and jre 1.8.0_144

I posted the same question on the original c libsodium library repo jedisct1/libsodium#634. But I figured I'd ask here since I'm using this library. I'm on 32-bit win10 running this in IntelliJ. I installed the c library myself since any documentation for windows is non-existant but when I run the TestSodiumLibrary it fails on 13 tests all with the same error relating to incorrect sizes of nonces and salts. Something like "com.muquit.libsodiumjna.exceptions.SodiumLibraryException: salt is 32, it must be 63310704161062944 bytes". So my thinking is I probably didn't setup access to the c library properly, but I don't have any way of being sure. I was hoping maybe someone would have an idea as to why the incorrect byte size is being read from c in the Java project. I.e for cryptoPwhashScrypt it sets long salt_length to sodium().crypto_pwhash_scryptsalsa208sha256_saltbytes(). In c this is 32U, in java its something like 143250559619563552 since the value is never constant per compilation.

I feel blind, but I'm not seeing where/how to use iterations/cost for Argon2, if it's built in.

Am I missing something?

Issue when im decrypting a key of 184 bytes. the allowed is 32 bytes. how can we change the constant NativeLong crypto_box_secretkeybytes() into 184
