sm4_encrypt_ecb_base64: SM4 Encrypt/Decrypt - hex and base64

Description

For ease of use, we have provided functions to encrypt data into hex or base64 format and decrypt them from these formats.

Usage

sm4_encrypt_ecb_base64(input_data, key)
sm4_encrypt_ecb_hex(input_data, key)
sm4_decrypt_ecb_base64(input_data, key)
sm4_decrypt_ecb_hex(input_data, key)
sm4_encrypt_cbc_base64(input_data, key, iv)
sm4_encrypt_cbc_hex(input_data, key, iv)
sm4_decrypt_cbc_base64(input_data, key, iv)
sm4_decrypt_cbc_hex(input_data, key, iv)

Value

sm4_encrypt_ecb_base64

returns a base64 string of the cipher text using ecb mode

sm4_encrypt_ecb_hex

returns a hex string of the cipher text using ecb mode

sm4_decrypt_ecb_base64

returns a raw vector of the plain text

sm4_decrypt_ecb_hex

returns a raw vector of the plain text

sm4_encrypt_cbc_base64

returns a base64 string of the cipher text using cbc mode

sm4_encrypt_cbc_hex

returns a hex string of the cipher text using cbc mode

sm4_decrypt_cbc_base64

returns a raw vector of the plain text

sm4_decrypt_cbc_hex

Arguments

input_data

for encrypt, data is a raw vector, for decrypt, data is a hex or base64 string

key

the key, must be a raw vector of length 16

iv

the initialization vector, must be a raw vector of 16
