ecdsa/ecdh: Use SHA256 override if known noncefp/hashfp is passed

This small change makes Bitcoin's cryptographic library treat two built-in functions (the default ECDSA nonce generator and the default ECDH hash function) as 'default' choices even when a caller explicitly passes them. The practical effec…

SECURITY.md: Align the table

This commit is purely cosmetic: it adjusts the spacing in a markdown table inside the SECURITY.md file so the columns line up visually. No code, keys, fingerprints, instructions, or security policy content were changed.

tests: Fix GCC 17 snapshot warning

This is a test-only cleanup. The commit removes a unit test pattern that passed a stack-allocated (non-malloc) scratch-space object to a destroy function that could call free(), which is undefined behavior. The test logic is reimplemented …

ecmult: Document and test ng=NULL in ecmult

This commit only adds a documentation comment and extra test cases for an already-supported calling convention of an internal elliptic-curve multiplication function. It does not change any behavior or fix any bug.
