Standard tools for deterministic RSA key generation using seed? I'd like to resuse the mnemonic I have from bip39 for crypto in other domains such as ssh and tls, etc.  Are there standard tools (ie, openssl) to deterministically generate rsa key/pairs given a seed value?  I know technically it is possible using PBKDF2 to create a PRNG etc, but I'm definitely not looking to roll my own crypto.
I'm just wondering if there is an easy way using openssl or gnu to reuse my bip39 mnemonic in other contexts besides crypto.  Or if there is a way of converting the derived key pairs from one algorithm into rsa using standard libraries.
Thanks.
For generating RSA keypairs from BIP39 mnemonics, a quick search give me three tools. but it is a bad method for deriving key pairs. A better method is using Key Derivation Functions with a standard tool like GnuPG.
