crypto_has_aead(9)

💖 NAME 💖

okay so bestie, meet crypto_has_aead — straight out of the Kernel API Manual, no cap. Its whole entire thing? Search for the availability of an aead. That’s it. That’s the vibe. 💅

✨ SYNOPSIS ✨

int crypto_has_aead (const char *alg_name , u32 type , u32 mask );

bestie look at those three little args, they’re literally the whole plot 🎀

🎀 ARGUMENTS 🎀

• alg_name — this is the cra_name / name or cra_driver_name / driver name of the aead. yes, either flavor, she accepts both 💖
• type — specifies the type of the aead. iconic specificity.
• mask — specifies the mask for the aead. the matching energy we need ✨

🦋 RETURN 🦋

It gives you true when the aead is known to the kernel crypto API; false otherwise. fr fr, that’s the whole return situation 🌸
