could you please take a look at this issue

Possible keypair bug

Why do you use

 mysecret[0] &= 248;
 mysecret[31] &= 63;
 mysecret[31] |= 64;

to calculate the private key in crypto_sign_keypair when Bernstein, uses

 mysecret[0] &= 248;
 mysecret[31] &= 127;
 mysecret[31] |= 64;

Ability to specify private key

Please add the ability to specify the private key (previosly stored somewhere else) as well as getting the Public key derrived from the private that was manually set.

Build error on Node 10 and OpenSSL 1.1.1a

Fix for #18 as well as break in Windows build under Node 10. Fixes in PR #20.

Batch verification

I couldn't find the batch verification/signing feature of ed25519 in this implementation. Is it on the roadmap? I would help but I'm not very experienced in the field of cryptology at all.

Need to upgrade nan. Doesn't compile on node v0.12

Project needs new maintainer

Hey bro!

You created something the community loves and needs. But leaving pull request unanswered and ignore issues is a horror!

Your repository is used by 1.4k other packages. Therefore please fix the issues! It is a pain in the ass for all developers out there getting errors just because someone thought it would be could to write some OSS and doesn't maintain it.

That's not how OSS should work!

cheers

Error with Electron project

hi, in my project, I need use ed25519 library. If I run the program directly after npm install, an error will be reported:

Path for "C:\OpenSSL-Win64\lib\libeay32.lib" is hard-coded.

Now, I don't know if this is the right place, but someone, somewhere along the twisted chain of NodeJS dependencies, decided it was a good idea to hard-code a library's path.

I installed OpenSSL, yet I got an error.

LINK : fatal error LNK1181: cannot open input file 'C:\OpenSSL-Win64\lib\libeay32.lib' [C:\Users\natob\Documents\GitHub\GetEpona\Epona-js\node_modules\ed25519\build\ed25519.vcxproj]

Moreover, the library changed name with an updated OpenSSL version. Even if one was to install OpenSSL the way you want, it still wouldn't work because they'd need to install that one version that works.

Here's the full logs.

Windows Build Issue due to OpenSSL Library Name Change

In Windows, you get an install error if you are installing on a system with OpenSSL Version 1.1 or later installed. The problem is that OpenSSL has changed the name of a library file. I believe this can be fixed in the bindings.gyp file by changing line 88
from:
'-l<(openssl_root)/lib/libeay32.lib',
to:
'-l<(openssl_root)/lib/libcrypto.lib',
Or perhaps by having a test to check which of these libraries (if any) are installed and then select the installed one.

Is it necessary to even explicitly include this library? ed25519 seems to compile / install even if this is commented out.
