WebIn Crypto++ you're directly passing a broken key to ecb_encryptor. AES supports keys of 16, 24 and 32 bytes length and nothing in between. But you're providing a 10 byte key and tell Crypto++ that the key is actually 32 byte long. This probably results in a random key because the remaining bytes in memory probably contain some junk values.
