because you can convert HEX into WIF private key. 
Is there something similar what allows to create Segwit Bitcoin addresses from HEX? It is useful for those who want to dice wallet. 

user63569: Best similar and alternative is Bitwasp for PHP, with a few lines you can create much more than addresses and keys. 
Presently supported:

Bloom filters
Blocks, headers, and Merkle blocks
P2SH & Segregated witness scripts
An adaptable elliptic-curve library, using [PhpEcc] by default, or libsecp256k1 if the bindings are found
Support for building, parsing, signing/validating transactions
Deterministic signatures (RFC6979)
BIP32 and electrum (older type I) deterministic key algorithms
ScriptFactory for common input/output types, parser, interpreter, and classifiers
Supports bindings to libbitcoinconsensus
RPC bindings to Bitcoin Core's RPC
Bindings to Stratum (electrum) servers
Easy serialization to binary representation of most classes
SIGHASH types when creating transactions
Payment Protocol (BIP70)

Take a look bitcoin-php
