When making a message digest using the EVP_DigestInit_ex, EVP_DigestUpdate, EVP_DigestFinal_ex functions one ends up with a 20 byte (for instance, with sha1) data structure stored in the md array.
What I would like to know is if the order of those bytes is affected by underlying architecture of the system where this code runs? That is, if a file containing: (20 bytes from a message digest) (message which generated those 20 bytes) is generated on one machine, would an identical file be generated on every other machine, especially ones with different byte order? If not, what steps need to be taken to make this portable? Also, outside of the (possible) byte order issues with the digest output, I would like to know which if any message digest results also depend on byte order. For instance, I know blowfish does (acts in 32 bit chunks), what about sha1, md5, etc?
