PIPELINE Encoding & Decoding Beginner 2 steps

Convert Hex to Base64

When bridging binary representations between systems — for example a crypto library that emits hex digests and an API that expects Base64 — this two-step chain decodes the hex to its underlying bytes and then encodes those bytes as Base64. The intermediate byte representation is handled automatically by the platform.

What it solves

Decode a hexadecimal string into raw bytes and re-encode it as Base64 for compact transport.
