Bits
int (read-only)

Default Value: 0

The length of the key in bits.

Curve
string

Default Value: ""

This property specifies the name of the curve the EC key is built on.

Exportable
bool (read-only)

Default Value: False

Returns True if the key is exportable (can be serialized into an array of bytes), and False otherwise.

ID
byte[]

Default Value: ""

Provides access to a storage-specific key identifier. Key identifiers are used by cryptographic providers to refer to a particular key and/or distinguish between different keys. They are typically unique within a storage, but there is no guarantee that a particular cryptoprovider will conform to that (or will assign any key IDs at all).

IV
byte[]

Default Value: ""

The initialization vector (IV) of a symmetric key. This is normally a public part of a symmetric key, the idea of which is to introduce randomness to the encrypted data and/or serve as a first block in chaining ciphers.

Key
byte[] (read-only)

Default Value: ""

The byte array representation of the key. This may not be available for non-Exportable keys.

Nonce
byte[]

Default Value: ""

A nonce value associated with a key. It is similar to IV, but its only purpose is to introduce randomness.

Private
bool (read-only)

Default Value: False

Returns True if the object hosts a private key, and False otherwise.

Public
bool (read-only)

Default Value: False

Returns True if the object hosts a public key, and False otherwise.

Subject
byte[]

Default Value: ""

Returns the key subject. This is a cryptoprovider-dependent value, which normally aims to provide some user-friendly insight into the key owner.

Symmetric
bool (read-only)

Default Value: False

Returns True if the object contains a symmetric key, and False otherwise.

Valid
bool (read-only)

Default Value: False

Returns True if this key is valid. The term Valid highly depends on the kind of the key being stored. A symmetric key is considered valid if its length fits the algorithm being set. The validity of an RSA key also ensures that the RSA key elements (primes, exponents, and modulus) are consistent.

Constructors

public CryptoKey();
Public CryptoKey()

Creates an empty crypto key object.

Config Settings (CryptoKeyStorage Component)

The component accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

CryptoKeyStorage Config Settings

TempPath:   Path for storing temporary files.

This setting specifies an absolute path to the location on disk where temporary files are stored.

Base Config Settings

CheckKeyIntegrityBeforeUse:   Enables or disable private key integrity check before use.

This global property enables or disables private key material check before each signing operation. This slows down performance a bit, but prevents a selection of attacks on RSA keys where keys with unknown origins are used.

You can switch this property off to improve performance if your project only uses known, good private keys.

CookieCaching:   Specifies whether a cookie cache should be used for HTTP(S) transports.

Set this property to enable or disable cookies caching for the component.

Supported values are:

offNo caching (default)
localLocal caching
globalGlobal caching

Cookies:   Gets or sets local cookies for the component.

Use this property to get cookies from the internal cookie storage of the component 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 components 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 components.

LogDestination:   Specifies the debug log destination.

Contains a comma-separated list of values that specifies where debug log should be dumped.

Supported values are:

fileFile
consoleConsole
systemlogSystem Log (supported for Android only)
debuggerDebugger (supported for VCL for Windows and .Net)

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:

timeCurrent time
levelLevel
packagePackage name

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:

exclude-packageExclude a package specified in the value
exclude-moduleExclude a module specified in the value
exclude-classExclude a class specified in the value
exclude-methodExclude a method specified in the value
include-packageInclude a package specified in the value
include-moduleInclude a module specified in the value
include-classInclude a class specified in the value
include-methodInclude a method specified in the value

LogFlushMode:   Specifies the log flush mode.

Use this property to set the log flush mode. The following values are defined:

noneNo flush (caching only)
immediateImmediate flush (real-time logging)
maxcountFlush cached entries upon reaching LogMaxEventCount entries in the cache.

LogLevel:   Specifies the debug log level.

Use this property to provide the desired debug log level.

Supported values are:

noneNone (by default)
fatalSevere errors that cause premature termination.
errorOther runtime errors or unexpected conditions.
warningUse of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong".
infoInteresting runtime events (startup/shutdown).
debugDetailed information on flow of through the system.
traceMore detailed information.

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:

noneNo rotation
deleteolderDelete older entries from the cache upon reaching LogMaxEventCount
keepolderKeep older entries in the cache upon reaching LogMaxEventCount (newer entries are discarded)

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.

StaticDNS:   Specifies whether static DNS rules should be used.

Set this property to enable or disable static DNS rules for the component. Works only if UseOwnDNSResolver is set to true.

Supported values are:

noneNo static DNS rules (default)
localLocal static DNS rules
globalGlobal static DNS rules

StaticIPAddress[domain]:   Gets or sets an IP address for the specified domain name.

Use this property to get or set an IP address for the specified domain name in the internal (of the component) or global DNS rules storage depending on the StaticDNS value. The type of the IP address (IPv4 or IPv6) is determined automatically. If both addresses are available, they are devided by the | (pipe) character.

StaticIPAddresses:   Gets or sets all the static DNS rules.

Use this property to get static DNS rules from the current rules storage or restore them back between application sessions. If StaticDNS of the component is set to "local", the property returns/restores the rules from/to the internal storage of the component. If StaticDNS of the component is set to "global", the property returns/restores the rules from/to the GLOBAL storage. The rules list is returned and accepted in JSON format.

Tag:   Allows to store any custom data.

Use this config property to store any custom data.

TLSSessionGroup:   Specifies the group name of TLS sessions to be used for session resumption.

Use this property to limit the search of chached TLS sessions to the specified group. Sessions from other groups will be ignored. By default, all sessions are cached with an empty group name and available to all the components.

TLSSessionLifetime:   Specifies lifetime in seconds of the cached TLS session.

Use this property to specify how much time the TLS session should be kept in the session cache. After this time, the session expires and will be automatically removed from the cache. Default value is 300 seconds (5 minutes).

TLSSessionPurgeInterval:   Specifies how often the session cache should remove the expired TLS sessions.

Use this property to specify the time interval of purging the expired TLS sessions from the session cache. Default value is 60 seconds (1 minute).

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.
