Quoting from [0]:-
When you generate a key pair, you do so with:
1. a deterministic procedure;
2. a source of random bits.
For instance, with RSA, you generate p and q by creating
random odd numbers of the right size and looping until a prime
number is found. For a given random source, the whole process
is deterministic: given the same random bits, this will find
the same primes p and q.
Hence you can develop a PRNG seeded by a secret key K and use
it as random source for the key generation process. Whenever
you need the private key, you run the key generation process
again, using K as input. And voilà! Your private key, the one
you need to store, is now K.
