Input lenth error

[benittopremkumar]

input characters limited to 16,32,64 and so on otherwise it returns Input buffer too short.

This is a "limitation" of the Block cipher specification, as the name says, it operate on blocks, fixed-length blocks, which means fixed-length sizes for both input and key. You should pad your input.

If padding is a issue, you can try a Stream cipher, like Salsa20.
