Encryption with same key length

[Alfredomulet]

Hello there, which algorithm could I use to encrypt the data in a column keeping the Key length?

For example:

Decrypted: ONETIME
Encrypted: x95sf7w

All encryption algorithms I have used (RC2,RC4, DES, 3 DES, AES) use a key lenght over 40.

Cheers,
Alfredo

When you encrypt the data is will be longer than the source string.
