+* (crypto | x/auth) [#14372](https://github.com/cosmos/cosmos-sdk/pull/18194) Key checks on signatures antehandle


The changelog entry for pull request #14372 contains a typo or incomplete sentence: "Key checks on signatures antehandle." This should be corrected for clarity and completeness.

@@ -434,9 +427,8 @@ func TestAnteHandlerChecks(t *testing.T) {
 	// Secp256r1 keys that are not on curve will fail before even doing any operation i.e when trying to get the pubkey
 	testCases := []testCase{
 		{"secp256k1_onCurve", []cryptotypes.PrivKey{priv1}, msgs[0], []uint64{accs[0].GetAccountNumber()}, []uint64{0}, false, true},
-		{"secp256k1_NotOnCurve", []cryptotypes.PrivKey{priv12}, msgs[1], []uint64{accs[1].GetAccountNumber()}, []uint64{1}, true, true},


does this mean the key is always on the curve now or why remove the test case?

The new library does not allow the gneration of keys that are not in the curve, it triggers an error before generating the private key. Even bypassing it and generating a priv key that is not in the curve and assigning it as the key will fail if you try to get the pubkey/address

69-69: The entry for issue secp256k1: Not constant time #7051 correctly reflects the PR objective of enhancing the secp256k1 public key generation process for security reasons.

68-68: The entry for pull request perf: parse chain-id from big genesis file could be slow #18204 aligns with the summary mentioning the addition of a streaming JSON parser for parsing chain-id from the genesis file.

20-26: The addition of the secp256k1 import aligns with the PR objectives to enhance the secp256k1 public key generation process.

218-234: The changes to create an empty secp256k1 public key and marshal it into JSON align with the PR objectives to use the new secp256k1 implementation.

The secp256k1.PubKey{} struct should be initialized with a key of the correct size to prevent potential issues.

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation.
