Grammar tasks

Task A. Translate the sentences into Russian. State the functions of the gerund.

I'm sure we should go on making the experiment. As well as devising the Playfair cipher Charles Wheatstone invented the Wheatstone bridge. One starts performing the encryption by locating the two letters from the plaintext into matrix. The other approach to concealing plaintext structure in the ciphertext involves using several different substitutional ciphers. It is the periodicity of the repeating key which leads to the weakness in this method. Decryption is simply the reverse of the encryption process using the same secret key. When decrypting a route cipher, the receiver simply enters the ciphertext into the agreed-upon matrix. For encrypting elements of a plaintext made up of more than a single letter only digraphs (two successive letters ) have ever been used.

Task B. Find the gerund and the Complex Gerundial Constructions. Translate the sentences into Russian.

They announced that no one had chance of cracking the cipher. Wheatstone's inventing the cipher made development of substitution ciphers. They insisted on the encryption being made. It may be easier to remember this as the plaintext letters being at two corners of a rectangle. He succeeded in cryptoanalyzing running-key ciphers. The Greeks being the inventors of the first transpositional cipher wrote the first work "On the Defense of Fortifications". The first European manual on cryptography, consisting of a compilation of ciphers, was produced by Gabriele de Lavinde of Parma. Herbert Yardley organized and directed the US government's breaking of the codes during and after the First World War.
