public interface CMSEncryptionService

Interface for performing content-stream encryption and decryption.

Method Summary

Modifier and Type	Method and Description
InputStream	buildDecryptionInputStream(InputStream inputStream, Function<String,Key> keyById) Builds decrypted stream out of encrypted one.
OutputStream	buildEncryptionOutputStream(OutputStream dataContentStream, PublicKey publicKey, KeyID publicKeyID) Builds asymmetrically encrypted stream using public-key cryptography.
OutputStream	buildEncryptionOutputStream(OutputStream dataContentStream, SecretKey secretKey, KeyID secretKeyID) Builds symmetrically encrypted stream.

Method Detail

buildEncryptionOutputStream

OutputStream buildEncryptionOutputStream(OutputStream dataContentStream,
                                         PublicKey publicKey,
                                         KeyID publicKeyID)

Builds asymmetrically encrypted stream using public-key cryptography.

Parameters:

dataContentStream - Stream to encrypt

publicKey - User public key

publicKeyID - User public-key ID gets embedded into a stream, used for finding the private key to decrypt

Returns:

Encrypted stream that wraps dataContentStream

buildEncryptionOutputStream

OutputStream buildEncryptionOutputStream(OutputStream dataContentStream,
                                         SecretKey secretKey,
                                         KeyID secretKeyID)

Builds symmetrically encrypted stream.

Parameters:

dataContentStream - Stream to encrypt

secretKey - User secret key

secretKeyID - User key ID gets embedded into a stream, used for finding the key to decrypt

Returns:

Encrypted stream that wraps dataContentStream

buildDecryptionInputStream

InputStream buildDecryptionInputStream(InputStream inputStream,
                                       Function<String,Key> keyById)

Builds decrypted stream out of encrypted one.

Parameters:

inputStream - Stream to decrypt

keyById - Key to its ID mapping, will retrieve key for decryption using this

Returns:

Decrypted stream that wraps inputStream
