This package is part of NDNts, Named Data Networking libraries for the modern web.
SafeBag type allows importing and exporting private keys in ndn-cxx SafeBag format.
SafeBag encodes the private key as EncryptedPrivateKeyInfo ASN.1 structure, which may use one of many encryption algorithms.
The implementation for browsers only supports PBES2(PBKDF2(HMAC-SHA256),AES-256-CBC) encryption algorithm, which appears to be the default in OpenSSL 1.1.1.
NdnsecKeyChain type can access keys and certificates in ndn-cxx KeyChain.
It works by invoking the ndnsec command.
This feature only works in Node.js.
