crypto 3.0.4

Implementations of SHA, MD5, and HMAC cryptographic functions.

3.0.4

• Fix WebAssembly support.
• Require Dart 3.4

3.0.3

• Require Dart 2.19.0.
• Add topics to pubspec.yaml.

3.0.2

• Require Dart 2.14.0.
• Fix bug calculating hashes for content larger than 512MB when compiled to JS.

3.0.1

• Fix doc links in README.

3.0.0

• Stable release for null safety.
• Adds SHA-2 512/224 and SHA-2 512/256 from FIPS 180-4
• Removes newInstance instance members on some classes and updates documentation.

2.1.5

• Improve example and package description to address package site maintenance suggestions.

2.1.4

• BugFix: padding was incorrect for some SHA-512/328.

2.1.3

• Security vulnerability: Fixed constant-time comparison in Digest.

2.1.2

• Fix bug in SHA-2 384/512 blocksize.
• Added HMAC-SHA-2 test vectors

2.1.1+1

• Bump version number for publish mishap (spare file uploaded with pub publish).

2.1.1

• Added a workaround for a bug in DDC (used in build_web_compilers 1.x). This bug is not present in DDK (used in build_web_compilers 2.x).

2.1.0

• Added SHA384, and SHA512
• Add Sha224 + Refactor
• Support 32bit and 64bit operations for SHA384/51
• Add conditional imports
• De-listify 32bit allocations
• Add sha monte tests for 224,256,384, and 512

2.0.5

• Changed the max message size instead to 0x3ffffffffffff, which is the largest portable value for both JS and the Dart VM.

2.0.4

• Made max message size a BigNum instead of an int so that dart2js can compile with crypto.

2.0.3

• Updated SDK version to 2.0.0-dev.17.0

2.0.2+1

• Fix SDK constraint.

2.0.2

• Prepare HashSink implementation for limiting integers to 64 bits in Dart language.

2.0.1

• Support convert 2.0.0.

2.0.0

Note: There are no APIs in 2.0.0 that weren't also in 0.9.2. Packages that would use 2.0.0 as a lower bound should use 0.9.2 instead—for example, crypto: ">=0.9.2 <3.0.0".

• Hash and Hmac no longer extend ChunkedConverter.

1.1.1

• Properly close sinks passed to Hash.startChunkedConversion() when ByteConversionSink.close() is called.

1.1.0

• Hmac and Hash now extend the new ChunkedConverter class from dart:convert.

• Fix all strong mode warnings.

1.0.0

• All APIs that were deprecated in 0.9.2 have been removed. No new APIs have been added. Packages that would use 1.0.0 as a lower bound should use 0.9.2 instead—for example, crypto: ">=0.9.2 <2.0.0".

0.9.2+1

• Avoid core library methods that don't work on dart2js.

0.9.2

• Hash, MD5, SHA1, and SHA256 now implement Converter. They convert between List<int>s and the new Digest class, which represents a hash digest. The Converter APIs—Hash.convert() and Hash.startChunkedConversion—should be used in preference to the old APIs, which are now deprecated.

• SHA1, SHA256, and HMAC have been renamed to Sha1, Sha256, and Hmac, respectively. The old names still work, but are deprecated.

• Top-level sha1, sha256, and md5 fields have been added to make it easier to use those hash algorithms without having to instantiate new instances.

• Hashing now works correctly for input sizes up to 2^64 bytes.

Deprecations

• Hash.add, Hash.close, and Hash.newInstance are deprecated. Hash.convert should be used for hashing single values, and Hash.startChunkedConversion should be used for hashing streamed values.

• SHA1 and SHA256 are deprecated. Use the top-level sha1 and sha256 fields instead.

• While the MD5 class is not deprecated, the new MD5() constructor is. Use the top-level md5 field instead.

• HMAC is deprecated. Use Hmac instead.

• Base64Codec, Base64Encoder, Base64Decoder, Base64EncoderSink, Base64DecoderSink, and BASE64 are deprecated. Use the Base64 APIs in dart:convert instead.

• CryptoUtils is deprecated. Use the Base64 APIs in dart:convert and the hex APIs in the convert package instead.

0.9.1

• Base64 convert returns an Uint8List
• Base64 codec and encoder can now take an encodePaddingCharacter
• Implement a Base64 codec similar to codecs in 'dart:convert'

0.9.0

• ChangeLog starts here.
