Hi, We are using Keil compiler for 16-bit C167 infineon microcontroller and wishes to integrate DES encryption and DSA digital signature (i.e. SHA1, DES, and DSA modules).
1) Does OpenSSL provide 16-bit platform? Or rather, what is the best compilation/build options platform? Currently, we were concerned about the data types, definitions, declarations etc. 2) Does the OpenSSL requires any 64-bit operations for our applications mentioned above? In our case, "unsigned long" is 4 bytes, and compiler does not support 64 bit data type. 3) Is OpenSSL only applicable for operating system platform only? At 20 MHz clock frequency only, we are definitely concerned about whether our application can meet the demand. Thanks! Regards, Soon Heng
