What's the definition of crypto code?  For example, does an elisp
wrapper around GnuTLS count?  A wrapper around GnuPG?  Emacs contains
a MD5 implementation in C, is it "crypto"?  Or MD4, SHA-1?  Are
authentication mechanisms based on hashing, like CRAM-MD5, "crypto"?

In any case, files that may be relevant to look at include (not all
might have been part of Gnus 5.9):

ntlm.el
pgg*.el
sasl*.el
md4.el
hmac-*.el
imap.el
sieve-manage.el
tls.el
starttls.el
sha1-el.el
pop3.el
mml-sec.el
mml-smime.el
mml1991.el
mml2015.el
canlock.el
netrc.el
