asn1lib

• Relaxed the SDK constraint to allow Dart SDK 3.0 and above.

• ASN1OctetString.toString() now returns bytes as a list instead of throwing an exception when the contents can not be decoded as a UTF-8 string.

• The ASN1GeneralizedTime should not fail on decoding DateTime with single digit month, day, hour, minute or second.

• The ASN1Object.hashCode method now uses the encodedBytes to calculate the hash code. This ensures that two objects that are equal (have the same encoded bytes) have the same hash code.

• ASN1OctetString.toString() now returns the decoded bytes as a UTF-8 string. This is mostly for convenience / ergnomics. If you want the bytes as a list, use the valueBytes getter.

• Breaking Change for encoding`ASN1OctetString("some string"). The default encoding to octets now uses utf8. See README.md for more information.

• Added ASN1OctetString.utf8StringValue getter to return the decoded bytes as a UTF-8 string.

• Removed the dependency on the collection package (only used in tests)

• Fixes 73. You should be able to add more objects to a sequence and get encodedBytes between each add.

• Equals method needs to use deep list equality!

• Equals method was comparing unencoded object.

• Add equals and hashCode to ASN1Object

• Fixes #68

• Support the ability to parse objects with extended tags (more than one byte). #65
• Simplify by converting ASN1Length to Dart records

• Make a number of fields final that should not be changed.
• Add types to a few members.
• Remove nullability from a field fields.
• Require Dart 3.0

• Fix null assertion when accessing valueBytes before encodedBytes.

• Reverted parsing of APPLICATION tags to the older behavior. If the constructed bit is set, the tag is parsed as an ASN1Sequence. The recent updates broke LDAP ASN1 parsing.

• Adds classes to handle non primitive classes: ASN1Application,ASN1ContextSpecific, ASN1Private.
• This is a potential change in behavior for consumers that expect some of these classes to be parsed as primitive or sequence types. See [README.md]
• The encodeApplicationTagsAsObject option on ASN1Parser has been dropped as it is now the default. Consumers should reparse bytes they know to be a sequence, etc.

• Fix #62. Allow context specific tags to be cast to an asn1 sequence.

• Fix #57

• Fix #61. Adds a flag to the parser encodeApplicationTagsAsObject that will force APPLICATION objects to be encoded as ASN1Objects, skipping any attempt to create sequences.

• fix: Use the correct value for unusedBits in ASN1BitString.fromBytes

• Add optional flag whether to relax parsing, off by default, for backwards-compatibility

• Add ASN1BMPString support

• Better toString() for ASN1ObjectIdentifier

• Add ASN1NumericString support
