  Classical cryptography is a way of disguising the news done by the people
when there was no computer. The goal is to protect information by way of
encoding. This paper describesa modification of classical algorithms to make
cryptanalis difficult to steal undisclosed messages. There are three types of
classical algorithms that are combined affine chiper, Caesar chiper and chiper
transposition. Where for chiperteks affine chiper and Caesar chiper can be
looped as much as the initial key, because the result can be varied as much as
key value, then affine chiper and Caesar chiper in this case is dynamic. Then
the results of the affine and Caesar will be combined in the transposition
chiper matrix by applying the pattern of rice cultivation path and for
chipertext retrieval by finally applying the pattern of rice planting path. And
the final digit of the digit shown in the form of binary digits so that 5
characters can be changed to 80 digit bits are scrambled. Thus the cryptanalyst
will be more difficult and takes a very long time to hack information that has
been kept secret.
