Duplicate openssl smime -encrypt -binary -aes-256-cbc -in some_file.dat -out some_file.dat.enc -outform DER cert.crt

See more OpenSSL Examples

Demonstrates how to encrypt to binary DER using 256-bit AES (CBC mode) as the underlying symmetric encryption algorithm, to produce PKCS7 enveloped data (binary DER).

Duplicates the following openssl command:

openssl smime -encrypt -binary -aes-256-cbc -in some_file.dat -out some_file.dat.enc -outform DER cert.crt
