smimeasym 1.0.0

smimeasym S/MIME asymmetrical encryption

So the problem to solve is that I needed a function that encrypts an array of ubytes with multiple public keys. The resulting, encrypted, array of bytes, when saved to a file, should be decrypted-able by any private key matching any of the used public key. This should be possible with the openssl cli.

Usage

There are two main functions

ubyte[] smimeEncryption(ubyte[] buf, string[] publicKeyFilenames);

ubyte[] smimeDecryption(ubyte[] buf, string privateKeyFilename);

The opencli should be able to decrypt created files from the data from smimeEncryption with the following shell command

openssl smime -decrypt -in secrets.txt.enc -inform PEM -inkey bob.key
