WebAES provides 128 bit, 192 bit and 256 bit of secret key size for encryption. If you are selecting 128 bits for encryption, then the secret key must be of 16 bits long and 24 and 32 bits for 192 and 256 bits of key size respectively. For example if the key size is 128 then a valid secret key must be of 16 characters i.e. 16*8=128 bits
