The White House wants to ‘cryptographically verify’ videos of Joe Biden so viewers don’t mistake them for AI deepfakes::Biden’s AI advisor Ben Buchanan said a method of clearly verifying White House releases is “in the works.”

SHA family and MD5 do not have keys. SHA1 and MD5 are insecure due to structural weaknesses in the algorithm.
Also, 2048 bits apply to RSA asymmetric keypairs, but SHA1 is 160 bits with similarly sized internal state and SHA256 is as the name says 256 bits.
ECC is a public key algorithm which can have 256 bit keys.
Dilithium is indeed a post quantum digital signature algorithm, which would replace ECC and RSA. But you’d use it WITH a SHA256 hash (or SHA3).
Good catch, and appreciate the additional info!
