Debugging techniques and tools for Constantine cryptographic code. Use debugEcho, toHex, debug: template, and stack trace flags when debugging Nim crypto implementations.

Profile and identify performance bottlenecks in Constantine cryptographic code using metering and benchmarking tools. Use when optimizing cryptographic algorithms, analyzing hotspots, or comparing implementations against reference benchmarks.

Nim seq, arrays, openarray, slicing, and views best practices for zero-allocation cryptographic code. Use when working with buffers, slicing data, or managing memory in Constantine to avoid heap allocations and side-channels.

Constantine serialization and hex debugging conventions. Use when serializing cryptographic types, parsing bytes, debugging values with toHex, or working with BLS12-381, Banderwagon, or ECDSA codecs.
