Question: Create a Assembly Language program in x86 Tasm Dosbox using the Type 1 Font decryption algorithm to decrypt a read in text file. Use comments
Create a Assembly Language program in x86 Tasm Dosbox using the Type 1 Font decryption algorithm to decrypt a read in text file. Use comments to explain each line of code.
The Type 1 Font decrpytion 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; }
