cms.Clearance
via @MatthiasValvekens - Fixed calling
.dump(force=True)
when the value has undefined/unknowncore.Sequence
fields. Previously the value would be truncated, now the existing encoding is preserved. - Added sMIME capabilities (
1.2.840.113549.1.9.15
) support from RFC 2633 tocms.CMSAttribute
via Hellzed
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

TypeError
when trying to call.untag()
or.copy()
on acore.UTCTime()
orcore.GeneralizedTime()
, or a value containing one, when using Python 2
1.2.0
- Added
asn1crypto.load_order()
, which returns alist
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

now returns the value"rsaes_pkcs1v15"
for OID1.2.840.113549.1.1.1
instead of"rsa"
- Removed functionality to calculate public key values from private key
values. Alternatives have been added to oscrypto.

- Enhancements
- Significantly improved parsing of
core.UTCTime()
andcore.GeneralizedTime()
values that include timezones and fractional seconds util.timezone
has a more complete implementationcore.Choice()
may now be constructed by a 2-element tuple or a 1-key dict- Added
x509.Certificate().not_valid_before
andx509.Certificate().not_valid_after
- Added
core.BitString().unused_bits
- Added
keys.NamedCurve.register()
for non-mainstream curve OIDs - 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 returnedNone
due to the way the structure was designed.- Add support for explicit RSA SSA PSS (
1.2.840.113549.1.1.10
) tokeys.PublicKeyInfo()
andkeys.PrivateKeyInfo()

1.2.840.113549.1.1.7
) tocms.KeyEncryptionAlgorithmId()
- Add IKE Intermediate (
1.3.6.1.5.5.8.2.2
) tox509.KeyPurposeId()
x509.EmailAddress()
andx509.DNSName()
now handle invalidly-encoded values using tags forcore.PrintableString()
andcore.UTF8String()
- Add parameter structue from RFC 5084 for AES-CCM to
algos.EncryptionAlgorithm()
- Improved robustness of parsing broken
core.Sequence()
andcore.SequenceOf()
values
- Significantly improved parsing of
- Bug Fixes
- Fixed encoding of tag values over 30
core.IntegerBitString()
andcore.IntegerOctetString()
now restrict values to non-negative integers since negative values are not implemented- When copying or dumping a BER-encoded indefinite-length value,
automatically force re-encoding to DER. To ensure all nested values are
always DER-encoded,
.dump(True)
must be called. - Fix
UnboundLocalError
when callingx509.IPAddress().native
on an encoded value that has a length of zero - Fixed passing
class_
via unicode string name tocore.Asn1Value()
- Fixed a bug where EC private keys with leading null bytes would be
encoded in
keys.ECPrivateKey()
more narrowly than RFC 5915 requires - Fixed some edge-case bugs in
util.int_to_bytes()
x509.URI()
now only normalizes values when comparing- Fixed BER-decoding of indefinite length
core.BitString()
- Fixed DER-encoding of empty
core.BitString()
- Fixed a missing return value for
core.Choice().parse()
- Fixed
core.Choice().contents
working when the chosen alternative is acore.Choice()
also - Fixed parsing and encoding of nested
core.Choice()
objects - Fixed a bug causing
core.ObjectIdentifier().native
to sometimes not map the OID
- Packaging
wheel
,sdist
andbdist_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
andexplicit_class
attributes oncore.Asn1Value
no longer exist and were replaced by theimplicit
andexplicit
attributes. Field param dicts may use the newexplicit
andimplicit
keys, or the oldtag_type
andtag
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 ofcrl.TbsCertList
to be optional - Added the
x509.Certificate.sha256_fingerprint
property x509.Certificate.ocsp_urls
andx509.DistributionPoint.url
will now returnhttps://
,ldap://
andldaps://
URLs in addition tohttp://

functions for low-level integration - Added
asn1crypto.version
for version introspection without side-effects - Added

is specified (i.e. a "named bit list") to omit trailing zero bits. This fixes compliance of variousx509
structures with RFC 5280. - Corrected a side effect in
keys.PrivateKeyInfo.wrap()
that would cause the originalkeys.ECPrivateKey
structure to become corrupt core.IntegerOctetString

- 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 anx509.Name
