crypto_sig_keysize(9)

💖 NAME 💖

okay bestie, welcome to crypto_sig_keysize(9) from the Kernel API Manual 💅 this is the page for crypto_sig_keysize — literally the “Get key size” girlie ✨

✨ SYNOPSIS ✨

unsigned int crypto_sig_keysize (struct crypto_sig *tfm );

🎀 ARGUMENTS 🎀

• tfm — the signature tfm handle, and it has to be allocated with crypto_alloc_sig 🫶

🦋 DESCRIPTION 🦋

She returns the key size in bits, periodt 💖

This function assumes that the key is already set in the transformation. Like, the key has to already be there — that’s the vibe it’s operating on.

⚠️ bestie, real talk: if this function is called without a setkey or with a failed setkey, you may end up in a NULL dereference 😭 that is not the cute kind of plot twist, so pls be careful 🙈
