Hybrid cryptography: running classical and post-quantum together during the transition

Hybrid cryptography runs a classical and a post-quantum algorithm together during the migration, so a record stays secure if either one is broken. Standards bodies recommend it because a flaw in a young post-quantum scheme and a future quantum computer are both survivable.Originally published at https://mickai.co.uk/articles/hybrid-cryptography-classical-and-post-quantum-together.
