Method DecryptAESKey
DecryptAESKey(out Byte[], Byte[], Byte[], RSAParameters)
Decrypts the encrypted AES key (32bytes) by means of the preliminary document hash and a private RSA key.
Declaration
Error DecryptAESKey(out byte[] aesKey, byte[] encryptedAesKey, byte[] preliminaryDocumentHash, RSAParameters rsaParameters)Parameters
| Type | Name | Description |
|---|---|---|
| System.Byte[] | aesKey | The decrypted key. |
| System.Byte[] | encryptedAesKey | The encrypted AES key. |
| System.Byte[] | preliminaryDocumentHash | The preliminary document hash |
| System.Security.Cryptography.RSAParameters | rsaParameters | The parameters of the private RSA key. |
Returns
| Type | Description |
|---|---|
| Error | Error |
Remarks
The key is decrypted in two steps:
1. The given encrypted AES key is RSA decrypted.
2. The result is AES decrypted with the preliminary document hash as decryption key.
DecryptAESKey(out Byte[], Byte[], Byte[], String)
Decrypts the encrypted AES key (32bytes) by means of the preliminary document hash and a private RSA key parsed from a PEM file
