Abstract
An application of differential geometry in hiding text-data is presented in this paper. This application is a generalization of similar previously presented methods. Matrix valued functions of more than one variable are used in text hiding. This method is covered by the corresponding programs in the MATHEMATICA software package and compared with the previously presented method.

PublicKey[text_,message_,ch_,p_,q_,L_,CC_,R]:= Module[{pk}, u=MatricesPairsFunctions[PairsMatrices[ CompletePairs[HidePairs[ TextPairs[text,ch],ch],p,q],p,q],message[[2]]]; If[StringQ[u],pk=u,u=HadamardProduct[u]]; u=Hiding[u,L,CC,R,message[[1,1]], message[[1,2]],message[[1,3]]]; If[StringQ[pk],pk=pk,pk=u]; This program integrates all previous programs related to encryption and as a result brings back a public key if the entered variables are correct or a text message if some of the numerical parameters are not correctly assigned
Decrypting[message_, publickey_, L_, CC_, R_, ch_] := SetsText[PairsMessageSets[ PairsMessagePositions[ FactorsCharactersPositions[ Dehiding[publickey, message, L, CC, R], ch], message], message]]; This program integrates all previous programs related to encryption and as a result brings back the text encrypted by a public key
