summary: Support for ECDSA keys in PuTTY and PuTTYgen
class: wish: This is a request for an enhancement.
difficulty: tricky: Needs many tuits.
priority: medium: This should be fixed one day.

RFC 5656 defines elliptic-curve (ECDSA) key formats (host and user) for use with SSH-2, and associated ECDH key exchange methods. OpenSSH has supported these since 5.7.

PuTTY does not currently support these. It probably should.

The only niggle I (OSD) have is that I'm not 100% sure what the patent situation is. (Wikipedia has some words on the subject.)

A user reports that the French government computing security agency ANSSI has recommendations for configuring OpenSSH that prefer use of ECDSA keys.

Audit trail for this wish.
