During CSV wallet recovery, intermediate buffers from Buffer.from() and bs58.decode() containing raw private key bytes were left in memory after Keypair creation. These temporary buffers are now explicitly zeroed with .fill(0) immediately after use to minimize the window for key material exposure in process memory.

Closed as superseded by #75, which reapplies the corrected security hardening on top of current main. This avoids merging stale/conflicted branches and preserves the fixes with passing CI/CodeQL. |
