方法详细资料

addKeyPairDescMaterial

public void addKeyPairDescMaterial(KeyPair keyPair,
                          Map<String,String> description)

Add a key pair and its descrption for decrypting data.

参数:

keyPair - The RSA key pair.

description - The descripton of encryption materails.

encryptCEK

public void encryptCEK(ContentCryptoMaterialRW contentMaterialRW)

Encrypt the content encryption key(cek) and iv, and put the result into ContentCryptoMaterialRW.

指定者:

encryptCEK 在接口中 EncryptionMaterials

参数:

contentMaterialRW - The materials that contans all content crypto info, it must be constructed on outside and filled with the iv cek parameters. Then it will be builed with the encrypted cek ,encrypted iv, key wrap algorithm and encryption materials description by this method.

decryptCEK

public void decryptCEK(ContentCryptoMaterialRW contentMaterialRW)

Decrypt the encrypted content encryption key(cek) and encrypted iv and put the result into ContentCryptoMaterialRW.

指定者:

decryptCEK 在接口中 EncryptionMaterials

参数:

contentMaterialRW - The materials that contans all content crypto info, it must be constructed on outside and filled with the encrypted cek ,encrypted iv, key wrap algorithm, encryption materials description and cek generator algothrim. Then it will be builded with the cek and iv.

getPrivateKeyFromPemPKCS1
