The conventional wisdom is that the successful US cryptanalytic efforts
against Japanese naval codes was a closely-held secret.
Has the conventional wisdom forgotten that it was reported in the
Chicago Tribune in 1942?

This is equivalent to asking whether factoring reduces to RSA inversion.
That is, given access to an RSA inversion oracle, can

Hey,
Does anyone know of any OSS OS facilities for managing keys?
With ssh-agent and gpg-agent providing access to key storage
by inherited processes, and the keys themselves being vulnerable
as stored on-disk, I wonder if there isn't any more general facility
for doing key management and
