Application upgrade (appup) files are corrected for the
following applications: </p>
<p>
<c>asn1, common_test, compiler, crypto, debugger,
dialyzer, edoc, eldap, erl_docgen, et, eunit, gs, hipe,
inets, observer, odbc, os_mon, otp_mibs, parsetools,
percept, public_key, reltool, runtime_tools, ssh,
syntax_tools, test_server, tools, typer, webtool, wx,

<p>
A new test utility for testing appup files is added to
test_server. This is now used by most applications in
OTP.</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>

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>

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>

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>

the path to the user application. Also try to verify
subject-AltName, if unable to verify it let the
