krb5_derive_Ke(9)

okay so bestie, this is the krb5_derive_Ke(9) page from the Kernel API Manual, and it’s literally about deriving a key and tucking it into an skcipher. Short, sweet, cryptographic. 💅

🎀 NAME 🎀

krb5_derive_Ke — derive key Ke and install it into an skcipher ✨

🌸 SYNOPSIS 🌸

No cap, the function signature is:

int krb5_derive_Ke (const struct krb5_enctype *krb5 , const struct
       krb5_buffer *TK , u32 usage , struct krb5_buffer *key , gfp_t gfp );

🦋 ARGUMENTS 🦋

• krb5 — the encryption type to use. Iconic.
• TK — the base key.
• usage — the key usage number.
• key — a prepped buffer to store the key into.
• gfp — allocation restrictions.

💜 DESCRIPTION 💜

Derive the Kerberos Ke encryption key. The key is stored into the prepared buffer. That’s the whole plot, bestie — no extra lore. 🫶
