AES Cryptolib encrypted data doesn't decrypting by any other libraries on other platforms except Cryptolib itself

[Wladimir]

Hello everyone!

I encrypt the data with the AES-256 ECB algorithm using the X-Cube-Cryptolib library, while the library itself can decrypt the data correctly, and third-party libraries decrypt it incorrectly. I use 32 random bytes as the key.

I tried using Aes, AesManaged, Aes Crypto Provider, Rijndael, and RijndaelManaged in C# with the following parameters in the constructor

KeySize = 256;

Block Size = 128;

Mode = CipherMode.ECB;

Padding = PaddingMode.Zeros;

Key = key;

And on these sites by copying the bytes of the key and data from the debag:

Please tell me, maybe there is some error in the library. Thanks!

Best regards!
