[FreeBSD-Announce] HEADS-UP: OpenSSH DSA keys are deprecated in 12.0 and 11.0

[Devin Teske]

Which would you use?

ECDSA?

https://en.wikipedia.org/wiki/Elliptic_curve_cryptography <https://en.wikipedia.org/wiki/Elliptic_curve_cryptography>

"" In the wake of the exposure of Dual_EC_DRBG as "an NSA undercover operation", cryptography experts have also expressed concern over the security of the NIST recommended elliptic curves,[31] <https://en.wikipedia.org/wiki/Elliptic_curve_cryptography#cite_note-31> suggesting a return to encryption based on non-elliptic-curve groups. ""

Or perhaps RSA? (as des@ recommends)

(not necessarily to Glen but anyone that wants to answer)
