crypto_alloc_lskcipher(9)

okay so bestie 💖 this is crypto_alloc_lskcipher(9) from the Kernel API Manual, and it’s literally the page for grabbing a linear symmetric key cipher handle. slay. ✨

🎀 NAME 🎀

crypto_alloc_lskcipher — allocate linear symmetric key cipher handle

🦋 SYNOPSIS 🦋

struct crypto_lskcipher * crypto_alloc_lskcipher (const char *alg_name ,
u32 type , u32 mask );

🌸 ARGUMENTS 🌸

• alg_name — is the cra_name / name or cra_driver_name / driver name of the lskcipher. iykyk 💅
• type — specifies the type of the cipher.
• mask — specifies the mask for the cipher.

✨ DESCRIPTION ✨

Allocate a cipher handle for an lskcipher. The returned struct crypto_lskcipher is the cipher handle that is required for any subsequent API invocation for that lskcipher. like, this is your main-character handle for everything after 👑🫶

💜 RETURN 💜

allocated cipher handle in case of success; IS_ERR is true in case of an error, PTR_ERR returns the error code. so if things go off, check IS_ERR and let PTR_ERR spill the error code 😭✨
