+## 3.0.6
+
+* Move to `dart-lang/core` monorepo.
+
+## 3.0.5
+
+* Revert switch to enable fast "sinks" on Wasm because it breaks `dart2js` with
+  server mode.
+
+## 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.
