💅 DESCRIPTION 💅

lc_keyring_init() initializes a keyring for use with tokens and filters. it's giving "new beginnings", it's giving "your keyring could never be this fresh" ✨

lc_keyring_free() frees the storage allocated by lc_keyring_init(). yes bestie, what init giveth, free taketh away 🎀

keyring is a pointer to the keyring to initialize. just point at the thing and let it cook.

nkeys is the number of keys to allocate space for. pick your number, queen 👑

💀 ERRORS 💀
