Building a clean cryptg#28

hi, i am trying to build a general perpose cryptg so it can be imported in any platform and be use anywere, i think i almost got it, but i am getting an error when importing and using it in python using CDLL , the import is fine but when i call the function "encrypt_ige" i get "OSError: exception: access violation reading 0xFFFFFFFFFFFFFFFF" i could realy use your help. here is the code: ```rs /// Encrypts the input plain text with the 32 bytes key and IV. #[no_mangle] fn encrypt_ige(plain: &[u8], key: &[u8], iv: &[u8]) -> Vec<u8> { let mut key_array = [0; 32]; key_array.copy_from_slice(key); let mut iv_array = [0; 32]; iv_array.copy_from_slice(iv); let cipher = grammers_crypto::encrypt_ige(plain, &key_array, &iv_array); return cipher; } /// Decrypts the input cipher text with the 32 bytes key and IV. #[no_mangle] fn decrypt_ige(cipher: &[u8], key: &[u8], iv: &[u8]) -> Vec<u8> { let mut key_array = [0; 32]; key_array.copy_from_slice(key); let mut iv_array = [0; 32]; iv_array.copy_from_slice(iv); let plain = grammers_crypto::decrypt_ige(cipher, &key_array, &iv_array); return plain; } /// Factorizes the pair of primes ``pq`` into ``(p, q)``. #[no_mangle] fn factorize_pq_pair(pq: u64) -> (u64, u64) { grammers_crypto::factorize::factorize(pq) } ``` thank you very mush for your help.
