> It's been several years since we increased the default key sizes. Before shifting to PQC, NSA replaced its Suite B cryptography recommendations with the Commercial National Security Algorithm Suite which suggests:
> - SHA-384 for secure hashing
> - AES-256 for symmetric encryption
> - RSA with 3072 bit keys for digital signatures and for key exchange
> - Diffie Hellman (DH) with 3072 bit keys for key exchange
> - Elliptic curve [P-384] for key exchange (ECDH) and for digital signatures (ECDSA)
> So, this proposed changes made the suggested key size and algorithm changes. The changes are mostly in keytool, jarsigner and their regression tests, so @wangweij Could you please take a look?
> Thanks!
