Cryptography

Hi,

I have a file which contains 4 columns. I want to encrypt only the first column. The rest of data must be as it is.
flat file:

12234333 jakdjf 394839 343874
73746373 5jdkfdj 383993 958939
83473843 lksdjfj 388383 349399

so, 1 should be replace by 4, 2 with 8, 3 with 7.....
the output should effect only first column.
Please help me.
