The encryption equation for the elgamal encryption is: In affine cipher each letter in an alphabet is mapped to its numeric equivalent, encrypted using a simple mathematical function, and converted back to a letter. Web affine cipher is a type of monoalphabetic substitution cipher, where each letter in an alphabet is mapped to its numeric equivalent, encrypted using a simple mathematical. Web in mathematics, an affine function is defined by addition and multiplication of the variable (often x x) and written f(x)=ax+b f ( x) = a x + b.
