SPKAC stands for Signed Public Key and Challenge.

It is a format for sending a Certification Signing Request ... It is created using the little documented HTML keygen element[2] inside a number of Netscape compatible browsers.

- Wikipedia


Where did you read it in the context with crypto (cryptocurrency? or cryptography?) ?
I am not aware of any blockchain project somehow utilizing SPKAC.
This is something completely different (if you are comparing it with signature algorithms, etc.. in crypto(currencies)).

'The crypto module provides cryptographic functionality that includes a set of wrappers for OpenSSL's hash, HMAC, cipher, decipher, sign, and verify functions'.

Further, 'SPKAC is a Certificate Signing Request mechanism originally implemented by Netscape and was specified formally as part of HTML5's keygen element'.


Everything is explained in the link you have posted.
This is not related to cryptocurrencies. It is used for cryptographical functions (requesting, signing, verifying, ... signatures/authentication codes/etc.. ).

You mean we can not able to use this crypto library to develop any sample program of node js with blockchain. Can you provide me any valuable link so i can start creating private key and associated public in node js?

A Javascript bitcoin libary can be found here: https://github.com/bitcoinjs/bitcoinjs-lib.

An bitcoin core RPC client can be found here on NPM.


Both are the first results on google.
Quite a lot of repositories, code snippets, libaries, .. can be found pretty fast using google.
