Description

I tryed encrypt a text with a key with PHP code,then it is OK when decrypt it with Java and Object-C ,

 mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $bindkey, $text, MCRYPT_MODE_ECB )

I dont know why do you need a sha1 when I just want want decrypt a ECB mode string

local aes_default = aes:new(key,nil,
aes.cipher(128,"ecb"),aes.hash.sha1)

Research direction

Start by reproducing the PHP MCRYPT_RIJNDAEL_128 ECB encryption and the Lua aes:new(key, nil, aes.cipher(128, "ecb"), aes.hash.sha1) setup shown in the issue. Compare the resulting ciphertext and decryption behavior, then determine what compatibility or documentation change is needed so the expected ECB operation is clear and verifiable.
