WebCrypto GOST: Class: EnvelopedData

Constructor

new EnvelopedData()

The enveloped-data content type consists of an encrypted content of any type and encrypted content-encryption keys for one or more recipients. The combination of the encrypted content and one encrypted content-encryption key for a recipient is a "digital envelope" for that recipient. Any type of content can be enveloped for an arbitrary number of recipients using any of the supported key management techniques for each recipient.

The typical application of the enveloped-data content type will represent one or more recipients' digital envelopes on content of the data or signed-data content types.
