# Hex Encoding with Nethereum

Move between raw bytes, plain text and hex without guesswork

## What this does

Ethereum work throws hex strings at you constantly, and text, bytes and hex all have to line up exactly. This helps you convert between them in Nethereum, including the prefix and the big-integer hex type. Reach for it when a value arrives in one form and your code needs another.

### Top 3 things it does for you

- Turn a byte array into hex
- Read hex back into bytes
- Handle the hex prefix correctly

## About Hex Encoding with Nethereum

Converting between bytes, strings and hex is constant background work in Ethereum code. This skill covers those conversions in Nethereum: byte array to hex, hex back to bytes, and UTF-8 text encoded as hex.

It also covers the parts that are easy to get wrong around the edges of a conversion - the hex prefix, and working with HexBigInteger.
