Create aes key and iv
WebAesManaged already provides a method GenerateIV () to generate a satisfactory IV, which you can access from the IV property and prepend to the cipher text. Your PowerShell output of the Base64-encoded cipher text is 44 characters ( 16 byte IV + 16 byte ciphered message = 32 bytes -> 44 bytes in Base64).

So any cryptographically strong random number generator will do the trick. OpenSSL provides such a random number generator (which itself feeds on whatever the operating system provides, e.g. CryptGenRandom () on Windows or /dev/random and …
WebAug 14, 2013 · In principle AES keys can have any value. There are no "weak keys" as in (3)DES. Nor are there any bits that have a specific meaning as in (3)DES parity bits. So generating a key can be as simple as generating a byte array with random values, and creating a SecretKeySpec around it.
