crypto_sig_verify(9)

💖 NAME 💖

okay so bestie, welcome to the Kernel API Manual entry for crypto_sig_verify(9) — and her whole iconic job is literally to invoke signature verification. That’s it, that’s the vibe. ✨

✨ SYNOPSIS ✨

int crypto_sig_verify (struct crypto_sig *tfm , const void *src ,
unsigned int slen , const void *digest , unsigned int dlen );

🎀 ARGUMENTS 🎀

• tfm — the signature tfm handle, allocated with crypto_alloc_sig. slay, she’s the main character 💅
• src — source buffer.
• slen — source length.
• digest — digest.
• dlen — digest length.

🦋 DESCRIPTION 🦋

This function invokes the specific signature verification operation for a given algorithm. lowkey her whole purpose, and she ate. 👑

🌸 RETURN 🌸

Returns zero on verification success; returns an error code in case of error. no cap — 0 means she verified successfully, anything else means something went wrong 😭
