Node crypto / tiny AES round trip not working for 192/256 bit keys

[petef19]

I have created AES CBC ciphers via Node crypto w/ 16 byte keys - tiny AES decrypts the cipher correctly.
Ciphers created in Node crypto AES CBC using 24 byte or 32 bytes are NOT correctly decrypted in tiny AES, the derived padding is incorrect and the padding value is > 16...

is this a known limitation of the lib?

for context:
1 - I believe Node crypto is using OpenSSL.
2 - a Node crypto AES CBC round trip using 16/24/32 byte keys works
3 - a tiny AES round AES CBC trip using 16/24/32 byte keys works
4 - Node<->tiny 16 byte key AES CBC round trip works
5 - Node<->tiny 24|32 byte key AES CBC round trip does NOT work

example - AES CBC 192 bit:

std::string c_b64 = "6l9sPiHYKjK6LiIkJ7qcIg==";   // b64 cipher from Node crypto
std::string aek = "0.591.075170084239850551";  // AES key, 24 bytes
std::string iv = "0123456789abcdef";  // IV

tiny AES decrypting will NOT work but works in Node crypto

example - AES CBC 128bit:

std::string c_b64 = "0B/7mia9ITdfg4QG4AqL/w==";   // b64 cipher from Node crypto
std::string aek = "0.591.0751700842";  // AES key, 16 bytes
std::string iv = "0123456789abcdef";  // IV

tiny AES decrypting will work

got some help on SO, seems like by default the AES variant must be hardcoded in aes.h.
would love to see an example how to dynamically set the AES variant at runtime.
