43. Cryp_sm4_ecb

43.1. Function description:

This demo shows the operation of cryptographic processor, algorithm is SM4, algorithm mode including ECB.

  • Configure and prepare the plaintext data firstly, then start the encryption to get ciphertext data.

  • Compare the encryption result with the standard to verify the function of encryption.

  • Configure & prepare the key for decryption.

  • Configure & start the decryption, the ciphertext data is comming from encryption result.

  • Compare the decryption result with the plaintext to verify the function of decryption.

Note

For SM4_ECB mode decryption, the key has to be prepared firstly.

43.2. Test result:

After the operation of encryption and decryption, if the encryption data is same as the standard & the decryption result is same as the plaintext data, then print pass, if not print fail.

43.3. IO connection:

None
