Encrypt and envelope in VB.NET
I need to encrypt and envelope a zip file to be sent to an FTP area.
The guide they have provided us requires:
The data transmitted via SFTP will be encrypted and digitally signed in order to ensure its origin and confidentiality. The data will first be signed, with the PKCS7 format and then encrypted. The formats used to envelope the signed and encrypted data will comply with the PKCS # 7 standard; in particular, "signed data" formats will be used for signed data and "enveloped data" for encrypted data.
More specifically, the standard for data signature and encryption is the mixed S / MIME standard, with signature envelope and encryption complying with the PKCS # 7 v1.5 standard, with DER format encoding.
In the encryption phase the data are encrypted using a symmetric key algorithm, generated randomly from time to time. The key used is then inserted into the envelope, encrypted with the public RSA key of the recipient.
The asymmetric encryption algorithm, based on the private key - public key pair is RSA; the length of the keys is from 512 to 4096.
The symmetric encryption algorithms supported are: RC2, DES, DES-EDE-3, AES-128, AES-192, AES-256.
The supported HASH algorithms are: MD2, MD5, SHA-1, SHA-256, SHA-384, SHA-512.
Below is what we have available:
- (CF Responsabile) _firma.p12, which contains the key and certificate of signature of the Entity
- (CF Responsabile) _cifra.p12, which contains the key and certificate of the institution's figure
- sogeiunicocifra.pem, which contains the digit certificate
- CA.pem, which contains the certificate of the Certification Authority
I can't use OpenSSL and already have read tons of guides and examples but I don't undertand ho to use private/public keys to encrypt/envelope the zip file with p12 and PEM files.
Thank you in advice for every help.
