<p>
Add support for ISO oids 1.3.14.3.2.29 and 1.3.14.3.2.27
that are somtimes used instead of the PKCS defined oids
1.2.840.113549.1.1.5 and 1.2.840.10040.4.3. Add function
pkix_sign_types:/1 that translates oids to to algorithm
atoms ex:</p>
<p>
> public_key:pkix_sign_types({1,3,14,3,2,29}). {sha,rsa}</p>

Integrate elliptic curve contribution from Andreas
Schultz </p>
<p>
In order to be able to support elliptic curve cipher
suites in SSL/TLS, additions to handle elliptic curve
infrastructure has been added to public_key and crypto.</p>
<p>
This also has resulted in a rewrite of the crypto API to
gain consistency and remove unnecessary overhead. All OTP
applications using crypto has been updated to use the new
API.</p>
<p>
Impact: Elliptic curve cryptography (ECC) offers
equivalent security with smaller key sizes than other
public key algorithms. Smaller key sizes result in
savings for power, memory, bandwidth, and computational
cost that make ECC especially attractive for constrained
environments.</p>

<p>
Changed ssh implementation to use the public_key
application for all public key handling. This is also a
first step for enabling a callback API for supplying
public keys and handling keys protected with password
phrases. </p>
<p>
Additionally the test suites where improved so that they
do not copy the users keys to test server directories as
this is a security liability. Also ipv6 and file access
issues found in the process has been fixed.</p>
<p>
This change also solves OTP-7677 and OTP-7235</p>
<p>
This changes also involves some updates to public_keys
ssh-functions.</p>

Allows the public_key module to decode and encode RSA and
DSA keys encoded using the SubjectPublicKeyInfo format.
When pem_entry_encode is called on an RSA or DSA public
key type, the key is wrapped in the SubjectPublicKeyInfo
format.</p>

for a certificate, and updated public key asn1 spec to
handle inherited DSS-params.</p>

<p>
Changed ssl implementation to retain backwards
compatibility for old option {verify, 0} that shall be
equivalent to {verify, verify_none}, also separate the
cases unknown ca and selfsigned peer cert, and restored
return value of deprecated function
public_key:pem_to_der/1.</p>
<p>
Own Id: OTP-8858</p>

<p>
Better handling of v1 and v2 certificates. V1 and v2
certificates does not have any extensions so then
validate_extensions should just accept that there are
none and not end up in missing_basic_constraints clause.</p>
<p>
Own Id: OTP-8867</p>
</item>
<item>
<p>
Changed the verify fun so that it differentiate between
the peer certificate and CA certificates by using
valid_peer or valid as the second argument to the verify
fun. It may not always be trivial or even possible to
know when the peer certificate is reached otherwise.</p>

Added the functionality so that the verification fun will
be called when a certificate is considered valid by the
path validation to allow access to each certificate in
the path to the user application. Also try to verify
subject-AltName, if unable to verify it let the
application verify it.</p>
