changelog

1.4.0

• core.ObjectIdentifier and all derived classes now obey X.660 §7.6 and thus restrict the first arc to 0 to 2, and the second arc to less than 40 if the first arc is 0 or 1. This also fixes parsing of OIDs where the first arc is 2 and the second arc is greater than 39.
• Fixed keys.PublicKeyInfo.bit_size to return an int rather than a float on Python 3 when working with elliptic curve keys
• Fixed the asn1crypto-tests sdist on PyPi to work properly to generate a .whl

1.3.0

• Added encrypt_key_pref (1.2.840.113549.1.9.16.2.11) to cms.CMSAttributeType(), along with related structures
• Added Brainpool curves from RFC 5639 to keys.NamedCurve()
• Fixed x509.Certificate().subject_directory_attributes_value
• Fixed some incorrectly computed minimum elliptic curve primary key encoding sizes in keys.NamedCurve()
• Fixed a TypeError when trying to call .untag() or .copy() on a core.UTCTime() or core.GeneralizedTime(), or a value containing one, when using Python 2

1.2.0

• Added asn1crypto.load_order(), which returns a list of unicode strings of the names of the fully-qualified module names for all of submodules of the package. The module names are listed in their dependency load order. This is primarily intended for the sake of implementing hot reloading.

1.1.0

• Added User ID (0.9.2342.19200300.100.1.1) to x509.NameType()
• Added various EC named curves to keys.NamedCurve()

1.0.1

• Fix an absolute import in keys to a relative import

1.0.0

• Backwards Compatibility Breaks
  • cms.KeyEncryptionAlgorithmId().native now returns the value "rsaes_pkcs1v15" for OID 1.2.840.113549.1.1.1 instead of "rsa"
  • Removed functionality to calculate public key values from private key values. Alternatives have been added to oscrypto.
    • keys.PrivateKeyInfo().unwrap() is now oscrypto.asymmetric.PrivateKey().unwrap()
    • keys.PrivateKeyInfo().public_key is now oscrypto.asymmetric.PrivateKey().public_key.unwrap()
    • keys.PrivateKeyInfo().public_key_info is now oscrypto.asymmetric.PrivateKey().public_key.asn1
    • keys.PrivateKeyInfo().fingerprint is now oscrypto.asymmetric.PrivateKey().fingerprint
    • keys.PublicKeyInfo().unwrap() is now oscrypto.asymmetric.PublicKey().unwrap()
    • keys.PublicKeyInfo().fingerprint is now oscrypto.asymmetric.PublicKey().fingerprint
• Enhancements
  • Significantly improved parsing of core.UTCTime() and core.GeneralizedTime() values that include timezones and fractional seconds

  • No longer try to load optional performance dependency, libcrypto, on Mac or Linux
  • ocsp.CertStatus().native will now return meaningful unicode string values when the status choice is "good" or "unknown". Previously both returned None due to the way the structure was designed.
  • Add support for explicit RSA SSA PSS (1.2.840.113549.1.1.10) to keys.PublicKeyInfo() and keys.PrivateKeyInfo()
  • Added structures for nested SHA-256 Windows PE signatures to cms.CMSAttribute()

• Packaging
  • wheel, sdist and bdist_egg releases now all include LICENSE, sdist includes docs
  • Added asn1crypto_tests package to PyPi

0.24.0

• x509.Certificate().self_signed will no longer return "yes" under any circumstances. This helps prevent confusion since the library does not verify the signature. Instead a library like oscrypto should be used to confirm if a certificate is self-signed.
• Added various OIDs to x509.KeyPurposeId()
• Added x509.Certificate().private_key_usage_period_value
• Added structures for parsing common subject directory attributes for X.509 certificates, including x509.SubjectDirectoryAttribute()
• Added algos.AnyAlgorithmIdentifier() for situations where an algorithm identifier may contain a digest, signed digest or encryption algorithm OID
• Fixed a bug with x509.Certificate().subject_directory_attributes_value not returning the correct value
• Fixed a bug where explicitly-tagged fields in a core.Sequence() would not function properly when the field had a default value
• Fixed a bug with type checking in pem.armor()

0.23.0

• Backwards compatibility break: the tag_type, explicit_tag and explicit_class attributes on core.Asn1Value no longer exist and were replaced by the implicit and explicit attributes. Field param dicts may use the new explicit and implicit keys, or the old tag_type and tag keys. The attribute changes will likely to have little to no impact since they were primarily an implementation detail.
• Teletex strings used inside of X.509 certificates are now interpreted using Windows-1252 (a superset of ISO-8859-1). This enables compatibility with certificates generated by OpenSSL. Strict parsing of Teletex strings can be retained by using the x509.strict_teletex() context manager.
• Added support for nested explicit tagging, supporting values that are defined with explicit tagging and then added as a field of another structure using explicit tagging.
• Fixed a UnicodeDecodeError when trying to find the (optional) dependency OpenSSL on Python 2
• Fixed next_update field of crl.TbsCertList to be optional
• Added the x509.Certificate.sha256_fingerprint property
• x509.Certificate.ocsp_urls and x509.DistributionPoint.url will now return https://, ldap:// and ldaps:// URLs in addition to http://.
• Added CMS Attribute Protection definitions from RFC 6211
• Added OIDs from RFC 6962

0.22.0

• Added parser.peek()
• Implemented proper support for BER-encoded indefinite length strings of all kinds - core.BitString, core.OctetString and all of the core classes that are natively represented as Python unicode strings
• Fixed a bug with encoding LDAP URLs in x509.URI
• Correct x509.DNSName to allow a leading ., such as when used with x509.NameConstraints
• Fixed an issue with dumping the parsed contents of core.Any when explicitly tagged

• Added support for 2.16.840.1.113894.746875.1.1 OID to pkcs12.AttributeType

0.21.0

• Added core.load() for loading standard, universal types without knowing the spec beforehand

• Added asn1crypto.version for version introspection without side-effects
• Added algos.DSASignature

0.20.0

• Added support for year 0
• Added the OID for unique identifier to x509.NameType

• Corrected a side effect in keys.PrivateKeyInfo.wrap() that would cause the original keys.ECPrivateKey structure to become corrupt
• core.IntegerOctetString now correctly encodes the integer as an unsigned value when converting to bytes. Previously decoding was unsigned, but encoding was signed.

• Added support for the name_distinguisher, telephone_number and organization_identifier OIDs to x509.Name
• Fixed x509.Name.native to not accidentally create nested lists when three of more values for a single type are part of the name
• x509.Name.human_friendly now reverses the order of fields when the data in an x509.Name was encoded in most-specific to least-specific order, which is the opposite of the standard way of least-specific to most-specific.
• x509.NameType.human_friendly no longer raises an exception when an unknown OID is encountered
• Raise a ValueError when parsing a core.Set and an unknown field is encountered

0.15.0
