Hello! I'd like to create a DER-encoded PKCS7 message with the signedData and envelopedData chaining. openssl documentation advises
* Sign and encrypt mail: * * openssl smime -sign -in ml.txt -signer my.pem -text \ | openssl smime -encrypt -out mail.msg \ -from st...@openssl.org -to some...@somewhere \ -subject "Signed and Encrypted message" -des3 user.pem * But I need in encryption and signing of the binary payment file which intended to be transferred by a transport different from e-mail. How can I create DER-encoded binary PKCS7 message with a chained enveloping and signing of the binary data using openssl? What chaining way is preferable from the thirdparty systems compatibility point of view? - Specify signed content type as data and signed content as octet string of the enveloped data bytes. - Specify signed content type as envelopedData and signed content as enveloped data itself. Thanks! Alexey Svatseff.
