Function ffi_encrypt_data 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn ffi_encrypt_data(
    passphrase: *const c_char,
    input_ptr: *const u8,
    input_len: usize,
    out_len: *mut usize,
) -> *mut u8

Encrypts data using the given passphrase.

Safety

• passphrase must be a valid null-terminated C string
• input_ptr must point to valid memory of at least input_len bytes
• out_len must be a valid pointer to write the output length

Returns

• Non-null pointer to encrypted bytes on success
• NULL on error (invalid input or panic)
