AES_CMAC.H(3)

📦 version 1.5.0, in opensuse-leap 16.0

💖 NAME 💖

ok so this is the manual page for /home/abuild/rpmbuild/BUILD/libzpc-legacy-1.5.0-build/libzpc-1.5.0/include/zpc/aes_cmac.h — it's literally the AES-CMAC API, bestie. it lives in the Library Functions Manual, and yeah the header path is long enough to need its own zip code, we move 💅

🦋 SYNOPSIS 🦋

✨ Functions ✨

int zpc_aes_cmac_alloc (struct zpc_aes_cmac **ctx)
int zpc_aes_cmac_set_key (struct zpc_aes_cmac *ctx, struct zpc_aes_key
    *key)
int zpc_aes_cmac_sign (struct zpc_aes_cmac *ctx, unsigned char *mac,
    size_t maclen, const unsigned char *msg, size_t msglen)
int zpc_aes_cmac_verify (struct zpc_aes_cmac *ctx, const unsigned char
    *mac, size_t maclen, const unsigned char *msg, size_t msglen)
void zpc_aes_cmac_free (struct zpc_aes_cmac **ctx)

🌸 Detailed Description 🌸

AES-CMAC API. periodt.

ok so picture this: it's the Message authentication API for the Cipher-based Message Authentication Code (CMAC) [3], and it's based on the Advanced Encryption Standard (AES) block cipher [1]. that's the whole vibe 🫶

Definition in file aes_cmac.h.

👑 Function Documentation 👑

💜 int zpc_aes_cmac_alloc (struct zpc_aes_cmac ** ctx)

Allocate a new context for an AES-CMAC operation. fresh context, fresh start, main character energy ✨

Parameters

  • ctx — AES-CMAC context

Returns

0 on success. Otherwise, a non-zero error code is returned.

💜 int zpc_aes_cmac_set_key (struct zpc_aes_cmac * ctx, struct zpc_aes_key * key)

Set the key to be used in the context of an AES-CMAC operation. give it the key, it handles the rest 💅

Parameters

  • ctx — AES-CMAC context
  • key — AES key

Returns

0 on success. Otherwise, a non-zero error code is returned.

💜 int zpc_aes_cmac_sign (struct zpc_aes_cmac * ctx, unsigned char * mac, size_t maclen, const unsigned char * msg, size_t msglen)

Do an AES-CMAC signing operation. sign it, slay it, done 🔥

Parameters

  • ctx — AES-CMAC context
  • mac — message authentication code
  • maclen — message authentication code length [bytes]
  • msg — message
  • msglen — message length [bytes]

Returns

0 on success. Otherwise, a non-zero error code is returned.

💜 int zpc_aes_cmac_verify (struct zpc_aes_cmac * ctx, const unsigned char * mac, size_t maclen, const unsigned char * msg, size_t msglen)

Do an AES-CMAC verify operation. the vibe check of the crypto world, fr fr 🧚

Parameters

  • ctx — AES-CMAC context
  • mac — message authentication code
  • maclen — message authentication code length [bytes]
  • msg — message
  • msglen — message length [bytes]

Returns

0 on success. Otherwise, a non-zero error code is returned.

💜 void zpc_aes_cmac_free (struct zpc_aes_cmac ** ctx)

Free an AES-CMAC context. clean up after yourself, we love a tidy icon 🎀

Parameters

  • ctx — AES-CMAC context
