Is it possible to perform public key encryption flow for elliptic-curve cryptography? https://en.wikipedia.org/wiki/Public-key_cryptography I need to implement the following scenario: Alice ...
Encrypt some string with several Public Keys and decrypt with any of Private key? [closed]
I need to encrypt some string, let's say "Hello world" with several Public Keys and be able to decrypt this hash with any of Private Keys. Could you please tell if it possible and if so, the way to do ...
What is done to create a stellar AccountID aside from the generated raw secret and derived pub/priv key?
I am curious on what is done when a public/private key pair is created on Stellar. I understand a key pair is generated with ed25519, but why are there additional pre-fix/postfix involved? Why would ...
What are the differences between Ripple and Stellar addresses
What are the differences between Ripple and Stellar public/private key pairs? I understand the cryptography and libraries that Ripple and Stellar use are quite similar, but are they practically ...
