Hi, This is for AS2, specifically Signed, then Encrypted message.
Before I encrypt I simply checksum SHA1 the file with the muitipart content: EDI data on first part and signature on second. Mime Headers are canonical <cr><lf> at end of each mime header. Signature is binary because my trading partner wants it like that. Anyway. There is a whole package with multipart content, boundaries, etc. I attached it here: http://www.nabble.com/file/p17994998/mictest.txt mictest.txt Ok, if you do a SHA1 over it you get 229585b2927684ac1f8dae4290e3e70d6d9cb53f and if the sha1 is run as binary to then be injected in a base64 encoder (openssl sha1 -binary mictest.txt|openssl enc -a, you get: IpWFspJ2hKwfja5CkOPnDW2ctT8= Though, my trading partner with his WPG says that's not the value of the MIC, he gets "Uiaz1kOChhlSb/f3SJsmJ/O/8SI=" instead. Because the message is encrypted (asymetric, so one needs a certificate and private key to open) , the decryption brings out a quite monolithic unit, headers are canonical and there is a <cr><lf> after the last boundary too, ¿what then could be the error in the MIC calculation?
