Does the history explain itself?

Message quality measures whether a commit identifies its scope, purpose, rationale, testing, and supporting references. It does not change the security-severity score.

0a70c578514c3ecfedac508045397b627071e265 Split decode into build_base256 (Mitchell Bagot)

Pull request description:

At present, base58 has only encoding functionality in no-alloc builds. In order to allow decoding of known size data from base58 without an allocator, the base58 crate needs a decoder function like hex's decode_to_array. Such a function has more failure modes than the alloc decode_check function, so new error types are required also.

- Patch 1 splits the existing decode function into a private build_base256 function that writes to a provided scratch buffer.
- Patch 1 introduces decode_check_to_array function for decoding short (<128 char) base58 strings to byte arrays, and associated error types.
- Patch 2 adds tests to cover the new function.
- Patch 3 renames Error to DecodeCheckError, retaining a deprecated type alias.

dc21841b46abc39c49ed7075131f1ac46416137f hashes: add sha256::Midstate::SHA256_IV constant (Andrew Poelstra)

Pull request description:

Adds a new `Midstate::SHA256_IV` constant which allows you to construct a midstate equivalent to a new empty sha256 engine. Then adds `update` methods to `Midstate` which allow you to "ratchet forward" arbitrary midstates, 64 bytes at a time, by hashing the data. There is one fast method and two slow constfn methods.

The motivation is that in Elements we have many Merkle roots which are computed using sha256 midstates, which is safe to do because we're using domain-separated hashes and because our internal nodes are always hashes of exactly 64 bytes of data, which do not not need any length-suffixing. In rust-simplicity we have several such Merkle root types, many of which have a huge pile of precomputed constants, but whose constructors are forced to be non-`const`, which limits their use in generic contexts.

It's maybe a bit uncouth for me to just add some methods I need and cut a new release in a 1.x crate, but

* we have taken great pains to keep `hashes` out of other crates' public APIs, so its stability is not as paramount as it would be for encoding or units, say
* all the new methods (and one constant) are on the `Midstate` type, which is a "don't touch this unless you are a cryptographer" part of the API and already has some ugly methods
* the additions seem pretty reasonable to me, assuming you accept that we have a `Midstate` type at all; essentially they generalize the already-existing `hash_tag` method
* I am BDFL of this project

Commit message · Mitchell Bagot

Rename Error to DecodeCheckError

The Error type in base58 represents an error that can occur when
decoding a base58check string. Since there now exists the
DecodeCheckArrayError for errors that can occur when decoding in
allocless builds, the main error type should also be renamed to clarify
its exact use.

Rename Error to DecodeCheckError. Add deprecated type alias Error for
DecodeCheckError.

Security candidatehashes: add sha256::Midstate::SHA256_IV constantby Andrew Poelstra · dc21841b · Jul 31, 2026 · 3 filesMessage 78 · AdequateTriage 15Details
Commit message · Andrew Poelstra

hashes: add sha256::Midstate::SHA256_IV constant

Add a unit test for the new constant. Rename the internal-only function
compute_midstate_unoptimized to update_midstate_unoptimized, and change
call sites to call it with the new SHA256_IV constant.

This lets us "ratchet forward" arbitrary midstates in const contexts. The
next commit will expose this general functionality in a correct way (by
enforcing lengths). I would like this in rust-simplicity, so I can compute
various Merkle roots in const contexts.

Commit message · Mitchell Bagot

Split Address into an extension trait

The Address::from_script function relies on Params in the function
signature. Since Params can't be moved to addresses or primitives, this
function should be left behind in an extension trait for now.

Introduce AddressExt extension trait and move minimal functionality
from Address into it.

AI analysis · Informational 17/100

This commit is a straightforward API refactor in the BIP-32 (Bitcoin key derivation) code. It replaces a function that returned a raw secret key and chain code with one that returns a new structured type called XpubChildTweak. The actual cryptographic math and behavior remain the same; only the way callers receive the result has changed. There is no indication this fixes a security bug.

refactor(bip32): rename Xpub and Xpriv derivation methods

- Rename the xpriv and xpub derivation APIs to derive_child and derive_path
- Remove derive_priv, derive_xpriv, derive_pub, derive_xpub, and
ckd_pub. Callers should now use derive_child for single ChildNumber
derivation and derive_path for path derivation.

AI analysis · Informational 18/100

This is a routine code cleanup in a Bitcoin library. It renames key-derivation methods on extended public and private keys (Xpub/Xpriv) to clearer names and removes old aliases. There is no security bug being fixed and no new vulnerability introduced; it is purely a refactoring that may require downstream developers to update their code.

Commit message · Mitchell Bagot

Add try_push to Buffer trait

As part of the introduction of no-alloc encoding, the Buffer trait will
need a push function that can fail gracefully when it overflows. The
simplest solution is to introduce a try_push function that is infallible
for Vec and calls through to try_push on ArrayVec.

Add try_push function to Buffer trait.

AI analysis · Informational 15/100

This commit adds a new `try_push` method to an internal `Buffer` trait used during Base58 encoding. It is a straightforward, additive change that lets encoding code gracefully handle a full fixed-size buffer in no-allocation builds. There is no bug fix, no behavior change to existing code paths, and no security issue visible in the diff.
