Imports

xor_cipher(string text, string key) -> string

Apply XOR cipher to a given text using the provided key. Return the raw string result of XOR between text and key characters.

xor_cipher_hex(string text, string key) -> char*

Apply XOR cipher to a given text using the provided key. Return the result as a hexadecimal string.

random_salt(i32 length) -> string

Generate a random salt of the specified length. Return the generated salt as a string.

aes128_encrypt(string plaintext, string key) -> string

Encrypt data using AES-128 in ECB mode.

Takes plaintext and a 16-byte (128-bit) key.

Returns encrypted data as hexadecimal string.

aes128_decrypt(string ciphertext_hex, string key) -> string

Decrypt data using AES-128 in ECB mode.
