Question: Create a Assembly Language program using the Type 1 Font Encryption algorithm to read in text from a file, encrypt it then display the encrpyted
Create a Assembly Language program using the Type 1 Font Encryption algorithm to read in text from a file, encrypt it then display the encrpyted code. The assembler is x86 Tasm on DosBox
The Type 1 Font Encrpytion algorithm is depicted in C as
unsigned short int r; unsigned short int c1 = 52845; unsigned short int c2 = 22719; unsigned char Decrypt(cipher) unsigned char cipher; { unsigned char plain; plain = (cipher ^ (r>>8)); r = (cipher + r) * c1 + c2; return plain; }
