    Thanks to voltone for interop testing and related discussions.

    Own Id: OTP-18606 Aux Id: OTP-16875,OTP-16448

  • The exception reason when public_key:cacerts_get/0 failed has been improved.

    Own Id: OTP-18609 Aux Id: GH-7295, PR-7302

  • Key customization support has been extended to allow flexibility for implementers of for instance hardware security modules (HSM) or trusted platform modules (TPM).

    Own Id: OTP-18876 Aux Id: PR-7898, PR-7475

  • The documentation has been migrated to use Markdown and ExDoc.

    Own Id: OTP-18955 Aux Id: PR-8026

  • The existing function ssl:key_exporter_materials/4 is now documented and supported.


    Own Id: OTP-19016 Aux Id: PR-8233

  • Due to another attack on PKCS #1 v1.5 padding, known as the Marvin attack, about which we were alerted by Hubert Kario from Red Hat. You can find more details about the attack at Functions that may be vulnerable are now deprecated.

    Note that you might mitigate the problem by using appropriate versions of OpenSSL together with our software, but we recommend not using them at all.

    Also avoid using TLS versions prior to TLS-1.2 (not supported by default) and do not enable RSA-key exchange cipher suites (not supported by default).


    Own Id: OTP-19075

Public_Key 1.15.1

Fixed Bugs and Malfunctions

    Own Id: OTP-18718 Aux Id: GH-7546

  • Add check to disallow duplicate certs in a path

    Own Id: OTP-18723 Aux Id: GH-6394

Public_Key 1.14

Improvements and New Features

  • Handling of on_load modules during boot has been improved by adding an extra step in the boot order for embedded mode that runs all on_load handlers, instead of relying on explicit invocation of them, later, when the kernel supervision tree starts.

    This is mostly a code improvement and OTP internal simplification to avoid future bugs and to simplify code maintenance.

    Own Id: OTP-18447


Fixed Bugs and Malfunctions

  • ssl application will validate id-kp-serverAuth and id-kp-clientAuth extended key usage only in end entity certificates. public_key application will disallow "anyExtendedKeyUsage" for CA certificates that includes the extended key usage extension and marks it critical.

    Own Id: OTP-18739


Fixed Bugs and Malfunctions

  • Country name comparison shall be case insensitive

    Own Id: OTP-18718 Aux Id: GH-7546

Public_Key 1.13.3

Fixed Bugs and Malfunctions

  • As different solutions of verifying certificate revocation exists move the decode of 'CRLDistributionPoints' so that it will only be decode. When it is actually used in the verification process. This would enable interoperability with systems that use certificates with an invalid empty CRLDistributionPoints extension that they want to ignore and make verification by other means.

    Own Id: OTP-18316 Aux Id: GH-6402, PR-6883

  • public_key:pkix_path_validation validates certificates expiring after 2050

    Own Id: OTP-18356 Aux Id: GH-6403

  • Do not leave exit message in message queue after calling cacerts_load() on MacOS.

    Own Id: OTP-18392 Aux Id: GH-6656

Improvements and New Features

  • Replace size/1 with either tuple_size/1 or byte_size/1

    The size/1 BIF is not optimized by the JIT, and its use can result in worse types for Dialyzer.

    When one knows that the value being tested must be a tuple, tuple_size/1 should always be preferred.

    When one knows that the value being tested must be a binary, byte_size/1 should be preferred. However, byte_size/1 also accepts a bitstring (rounding up size to a whole number of bytes), so one must make sure that the call to byte_size/ is preceded by a call to is_binary/1 to ensure that bitstrings are rejected. Note that the compiler removes redundant calls to is_binary/1, so if one is not sure whether previous code had made sure that the argument is a binary, it does not harm to add an is_binary/1 test immediately before the call to byte_size/1.

    Own Id: OTP-18432 Aux Id: GH-6672,PR-6793,PR-6784,PR-6787,PR-6785,PR-6682,PR-6800,PR-6797,PR-6798,PR-6799,PR-6796,PR-6813,PR-6671,PR-6673,PR-6684,PR-6694,GH-6677,PR-6696,PR-6670,PR-6674

    Own Id: OTP-17890

  • The deprecated public_key functions ssh_decode/2, ssh_encode/2, ssh_hostkey_fingerprint/1 and ssh_hostkey_fingerprint/2 are removed.

    They are replaced by ssh_file:decode/2, ssh_file:encode/2, ssh:hostkey_fingerprint/1 and ssh:hostkey_fingerprint/2 respectively.

    Own Id: OTP-17657

Public_Key 1.11.2

Fixed Bugs and Malfunctions

  • public_key:pkix_sign/2 now honors the salt length from the provided input parameters. Earlier this could result in incorrect signatures if not using recommended defaults.

    Own Id: OTP-17242 Aux Id: GH-4500

Improvements and New Features

  • Add sanity check of trusted anchor certificate expiration to pkix_path_validation/3. Although the anchor is considered a trusted input this sanity check does provide extra security for the users of the public_key application as this property needs to be checked at time of usage and fits very well with the other checks performed here.

    Own Id: OTP-16907

  • Adjust generation of test certificates to conform to RFC 5280 rules for formatting of the certificates validity

    Own Id: OTP-17111

    Own Id: OTP-15776

Improvements and New Features

  • Add possibility to read PEM files encrypted with old PEM encryption using AES-256

    Own Id: OTP-13726

  • Relax decoding of certificates to so that "harmless" third party encoding errors may be accepted but not created by the public_key application. This adds acceptance of using an incorrect three character country code, the PKIX standard use two character country codes. It is also accepted that the country code is utf8 encoded but the specification says it should be ASCII.

    Own Id: OTP-15687 Aux Id: PR-2162

    Own Id: OTP-13381 Aux Id: seq13070

Public_Key 1.1

Improvements and New Features

  • The 'ecdsa-sha2-nistp256', 'ecdsa-sha2-nistp384' and 'ecdsa-sha2-nistp521' signature algorithms for ssh are implemented. See RFC 5656.

    Own Id: OTP-12936

  • There is now a file (public_key/priv/moduli) which lists size-generator-modulus triples. The purpose is to give servers the possibility to select the crypto primes randomly among a list of pregenerated triples. This reduces the risk for some attacks on diffie-hellman negotiation.

    See the reference manual for public_key:dh_gex_group/4 where the handling of this is described.

    The ssh server (ssh:daemon) uses this.

    Own Id: OTP-13054 Aux Id: OTP-13052

    Own Id: OTP-13132

Public_Key 1.0.1

Improvements and New Features

  • Document enhancements

    Own Id: OTP-12986

Public_Key 1.0

Improvements and New Features

  • public_key: Remove legacy switch compact_bit_string

    E.i bitstrings will not be decode as {Unused, Binary}, they are now Erlang bitstrings.

    Also the compact_bit_string implies the legacy_erlang_types switch So removing the switch will also make OCTET STRING values be represented as binaries.

    Undecoded open type will now be wrapped in a asn1_OPENTYPE tuple.

    This will change some values in records returned by the public_key API making this change a potentiall incompatibility.

    public_key:pkix_sign_types({1,3,14,3,2,29}). {sha,rsa}

    Own Id: OTP-10873

  • Integrate elliptic curve contribution from Andreas Schultz

    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.

    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.

    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.

  • Optimize RSA private key handling in crypto and public_key.

    Own Id: OTP-10065

Public_Key 0.15

Improvements and New Features

  • 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.

    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.

    This change also solves OTP-7677 and OTP-7235

    This changes also involves some updates to public_keys ssh-functions.

    Own Id: OTP-7884

  • 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.

  • 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.

    Own Id: OTP-8867

  • 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.
