* `wally_wif_to_bytes` — Convert a WIF to a private key (in bytes) * `wally_wif_to_bytes` — Convert a WIF to a private key (in bytes)
* `wally_wif_to_public_key` — Derive a public key (in bytes) from a WIF * `wally_wif_to_public_key` — Derive a public key (in bytes) from a WIF
Some have to do with the BIP32 HD-wallet format: ## Using BIP32 Functions
* `wally_bip32_key_to_address` — Derive a legacy address from a BIP32 key There are additional BIP32 HD-wallet functions, beyond what was covered in [§16.3: Using BIP32 in Libwally](16_3_Using_BIP32_in_Libwally.md).
* `wally_bip32_key_to_addr_segwit` — Derive a Segwit address from a BIP32 key
* `bip32_key_get_fingerprint` — Generate a BIP32 fingerprint for an extended key
* `bip32_key_serialize` — Transform an extended key into serialized bytes
* `bip32_key_strip_private_key` — Convert an extended private key to an extended public key
* `bip32_key_unserialize` — Transform serialized bytes into an extended key
There are also numerous various depending on you want to allocate memory of have Libwally doing the `_alloc` for you.
## Using BIP38 Functions
[BIP38](https://github.com/bitcoin/bips/blob/master/bip-0038.mediawiki) allows for the creation of password-protected private key. We do not teach it because we consider inserting this sort of human factor into key management dangerous. See [#SmartCustody](https://www.smartcustody.com/index.html).
The main functions are:
* `bip38_from_private_key` — Encode a private key using BIP38
* `bip38_to_private_key` — Decode a private key using BIP38
## Using Elements Function
## Using Elements Function2
Libwally can be compiled to be used with Blockstream's Elements, which includes access to its assets functions. Libwally can be compiled to be used with Blockstream's Elements, which includes access to its assets functions.
