Nonce reuse for different recipients?
I'm generating a new random symmetric key and want to pass that to multiple people using crypto_box_easy.
Is it okay to reuse the same (random) nonce for the same message and same sender but for different recipients? Can the same nonce be used for a…

Why does the NaCL Crypto Library source code reference header files that aren't in the code?
I'm looking through the code for the NaCL Crytpo Library, though I have almost no experience with C and C++. In some of the .cpp files, there are references to header files that are not in the source code. For example, in wrapper-box.cpp it has…

GET request successfully returns decrypted gist first time, but empty object after restarting the server
Using JavaScript and nacl libraries to get a GitHub gist and return the decrypted content. All nacl methods accept and return UINT8 arrays, so it is worth noting that the key is also a UINT8 array of 32 random bytes.

Access MAC keys in NaCl/libsodium
According to https://cr.yp.to/highspeed/naclcrypto-20090310.pdf, NaCl derives a MAC key from the shared secret and the nonce in crypto_box APIs.
Alice uses the first 32 bytes of the long stream (generated from the shared secret and nonce using…

Using NaCl to benchmark new crypto algorithm
For my master thesis, I have to implement some new Cryptographic functions so that I can have a brief overview of their performance. I have checked on the internet and it seems that the NaCl library was created for this purpose.
To be more precise…

Disable NaCl crypto library's CPU tuning
Is it possible to disable the automatic CPU-specific tuning in NaCl?
I would like to compile the reference .c ignoring any x86 .s (from qhasm) etc. where applicable.
Setting -march and -mtune or -mcpu appears not to be sufficient.
