Note Submitter: Matthias Barkhausen ---- To successfully sign and encrypt an plain text E-Mail to send to and to be able to read by Outlook and iOS Mail you need to first sign w/o headers and use the PKCS7_TEXT constant, then encrypt with headers and cipherid 3DES, then send with sendmail/ssmtp with -t option. Reason for 3DES ist that iOS (or Apple in general) doesnt further accept the RC40 default encryption openssl-pkcs7-encrypt is using. Outlook would decrypt such encryption, but iOS Mail just said "this mail has no content" and "install a profile containing your identity...". $headers = array("To" => ..., "From" => ..., "Subject" => ...); openssl_pkcs7_sign("msg.txt","signed.txt", $mMyCertFileToIncludeForRecipient,array($mMyPrivKeyFileAsPEM, "passphrase"),array(),PKCS7_TEXT); openssl_pkcs7_encrypt("signed.txt","enc.txt",$pubkeyContents,$headers,0,OPENSSL_CIPHER_3DES); shell_exec("ssmtp -t < enc.txt") #sendmail same syntax
