Use cases

Standalone key generator for nodes and peers.
As a library inside Iroha 2:
- generate peers IDs when default hasn't been provided.

Concerns

Strong Random Number Generator

One thing to keep in mind is that when generating keys, they need to be done using a cryptographically secure random number generator.

Ursa provides an ability to generate pseudo random numbers via BigNumber::rand which internally is OpenSSL BigNumRef::rand.
