public class DefaultMessagedecryptorEventListener implements MessagedecryptorEventListener { ... public void externalDecrypt(MessagedecryptorExternalDecryptEvent e) {} ... } public class MessagedecryptorExternalDecryptEvent { public String operationId; public String algorithm; public String pars; public String encryptedData; public String data; }
Remarks
Assign a handler to this event if you need to delegate a low-level decryption operation to an external, remote, or custom decryption engine. The handler receives a encrypted value in the EncryptedData parameter, and is expected to decrypt it and place the decrypted value into the Data parameter.
OperationId provides a comment about the operation and its origin. It depends on the exact component being used, and may be empty. Algorithm specifies the encryption algorithm being used, and Pars contain algorithm-dependent parameters.
The component uses base16 (hex) encoding for EncryptedData, Data, and Pars parameters. If your decryption engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the decryption.
A sample data encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

This provides extra protection layer for the protocol and diminishes the risk of private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use KeySecret to pass the key itself. The same KeyID/KeySecret pair should be used on the DCAuth side for the signing requests to be accepted. Note: The KeyID/KeySecret scheme is very similar to the AuthKey scheme used in various Cloud service providers to authenticate users. Example:
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
KeySecret String |
The pre-shared key used for DC request authentication. This key must be set and match the key used by the DCAuth counterpart for the scheme to work. Read more about configuring authentication in the KeyID topic. |

| Cookies: Gets or sets local cookies for the class (supported for HTTPClient, RESTClient and SOAPClient only).Use this property to get cookies from the internal cookie storage of the class and/or restore them back between application sessions. | ||||||||||||||||||||||||||||||
| DefDeriveKeyIterations: Specifies the default key derivation algorithm iteration count.This global property sets the default number of iterations for all supported key derivation algorithms. Note that you can provide the required number of iterations by using properties of the relevant key generation component; this global setting is used in scenarios where specific iteration count is not or cannot be provided. | ||||||||||||||||||||||||||||||
| EnableClientSideSSLFFDHE:
Enables or disables finite field DHE key exchange support in TLS clients.This global property enables or disables support for finite field DHE key exchange methods in TLS clients. FF DHE is a slower
algorithm if compared to EC DHE; enabling it may result in slower connections.
This setting only applies to sessions negotiated with TLS version 1.3. |
||||||||||||||||||||||||||||||
| GlobalCookies: Gets or sets global cookies for all the HTTP transports.Use this property to get cookies from the GLOBAL cookie storage or restore them back between application sessions. These cookies will be used by all the classes that have its CookieCaching property set to "global". | ||||||||||||||||||||||||||||||
| HttpUserAgent: Specifies the user agent name to be used by all HTTP clients.This global setting defines the User-Agent field of the HTTP request provides information about the software that initiates the request. This value will be used by all the HTTP clients including the ones used internally in other classes. | ||||||||||||||||||||||||||||||
| LogDestination:
Specifies the debug log destination.Contains a comma-separated list of values that specifies where debug log should be dumped.
Supported values are:
|
||||||||||||||||||||||||||||||
| LogDetails:
Specifies the debug log details to dump.Contains a comma-separated list of values that specifies which debug log details to dump.
Supported values are:
|
||||||||||||||||||||||||||||||
| LogFile: Specifies the debug log filename.Use this property to provide a path to the log file. | ||||||||||||||||||||||||||||||
| LogFilters:
Specifies the debug log filters.Contains a comma-separated list of value pairs ("name:value") that describe filters.
Supported filter names are:

LogFlushMode:
Specifies the log flush mode.Use this property to set the log flush mode. The following values are defined:
|
||||||||||||||||||||||||||||||
| LogLevel:
Specifies the debug log level.Use this property to provide the desired debug log level.
Supported values are:
|
||||||||||||||||||||||||||||||
| LogMaxEventCount:
Specifies the maximum number of events to cache before further action is taken.Use this property to specify the log event number threshold. This threshold may have different effects,
depending on the rotation setting and/or the flush mode.
The default value of this setting is 100. |

LogRotationMode:
Specifies the log rotation mode.Use this property to set the log rotation mode. The following values are defined:
|
||||||||||||||||||||||||||||||
| MaxASN1BufferLength: Specifies the maximal allowed length for ASN.1 primitive tag data.This global property limits the maximal allowed length for ASN.1 tag data for non-content-carrying structures, such as certificates, CRLs, or timestamps. It does not affect structures that can carry content, such as CMS/CAdES messages. This is a security property aiming at preventing DoS attacks. | ||||||||||||||||||||||||||||||
| MaxASN1TreeDepth: Specifies the maximal depth for processed ASN.1 trees.This global property limits the maximal depth of ASN.1 trees that the component can handle without throwing an error. This is a security property aiming at preventing DoS attacks. | ||||||||||||||||||||||||||||||
| OCSPHashAlgorithm: Specifies the hash algorithm to be used to identify certificates in OCSP requests.This global setting defines the hash algorithm to use in OCSP requests during chain validation. Some OCSP responders can only use older algorithms, in which case setting this property to SHA1 may be helpful. | ||||||||||||||||||||||||||||||
| Tag: Allows to store any custom data.Use this config property to store any custom data. | ||||||||||||||||||||||||||||||
| UseOwnDNSResolver: Specifies whether the client components should use own DNS resolver.Set this global property to false to force all the client components to use the DNS resolver provided by the target OS instead of using own one. | ||||||||||||||||||||||||||||||
| UseSharedSystemStorages: Specifies whether the validation engine should use a global per-process copy of the system certificate stores.Set this global property to false to make each validation run use its own copy of system certificate stores. | ||||||||||||||||||||||||||||||
| UseSystemOAEPAndPSS:
Enforces or disables the use of system-driven RSA OAEP and PSS computations.This global setting defines who is responsible for performing RSA-OAEP and RSA-PSS computations where the private key is stored in a Windows system store and is exportable.
If set to true, SBB will delegate the computations to Windows via a CryptoAPI call. Otherwise, it will export the key material and perform the computations
using its own OAEP/PSS implementation.
This setting only applies to certificates originating from a Windows system store. |
||||||||||||||||||||||||||||||
| UseSystemRandom: Enables or disables the use of the OS PRNG.Use this global property to enable or disable the use of operating system-driven pseudorandom number generation. |
