Description Property (PasswordVault Component)

The description of the vault.

Syntax

property Description: String read get_Description write set_Description;

Default Value

''

Remarks

Use this property to provide a textual description (comment) for the vault. This value is not encrypted even if the vault is.

EntryKey Property (PasswordVault Component)

Provides an encryption key for the current entry.

Syntax

property EntryKey: TBytes read get_EntryKey write set_EntryKey;

Remarks

Use this property to provide the encryption/decryption key for the current entry. This property is typically assigned from the EntryKeyNeeded event handler.

This property is automatically generated when a non-empty password is assigned to the EntryPassword property. This is because all entries, and the vault itself, are always encrypted with cryptographically strong keys, and if the user decides to use a password, it is converted to such key using a secure PBKDF function.

This property is not available at design time.

EntryPassword Property (PasswordVault Component)

Provides an encryption password for the current entry.

Syntax

property EntryPassword: String read get_EntryPassword write set_EntryPassword;

Default Value

''

Remarks

Use this property to provide the encryption/decryption password for the current entry. This property is typically assigned from the EntryKeyNeeded event handler.

See a comment in the EntryKey topic to find out how the passwords are used when encrypting entries.

FIPSMode Property (PasswordVault Component)

Reserved.

Syntax

property FIPSMode: Boolean read get_FIPSMode write set_FIPSMode;

Default Value

false

Remarks

This property is reserved for future use.

Key Property (PasswordVault Component)

Provides an encryption key for the vault.

Syntax

property Key: TBytes read get_Key write set_Key;

Remarks

Use this property to provide the 'master' key for the vault file. This property can be assigned from the KeyNeeded event handler.

The content of this property is automatically generated when a non-empty password is assigned to the Password property. This is because the vault file are always encrypted with a cryptographically strong key, and if the user decides to use a password, it is converted to such key using a secure PBKDF function first.

This property is not available at design time.

Password Property (PasswordVault Component)

Provides an encryption password for the vault file.

Syntax

property Password: String read get_Password write set_Password;

Default Value

''

Remarks

Use this property to provide the master password for the vault file. This property can be assigned from the KeyNeeded event handler.

See a comment in the Key topic to learn how the passwords are used when encrypting the vault file.

PlatformProtection Property (PasswordVault Component)

Enables platform-based protection of the master key.

Syntax

property PlatformProtection: Boolean read get_PlatformProtection write set_PlatformProtection;

Default Value

false

Remarks

Use this property to enable the platform-based protection for the main encryption key. The platform protection is currently only available on Windows, in the form of DPAPI in unmanaged editions, or ProtectedData in .NET Framework.

Title Property (PasswordVault Component)

The title of the vault.

Syntax

property Title: String read get_Title write set_Title;

Default Value

''

Remarks

Use this property to provide a title for your vault storage. This value is not encrypted event if the vault itself is.

AddEntry Method (PasswordVault Component)

Adds an entry to the vault.

Syntax

procedure AddEntry(EntryName: String);

Remarks

Use this method to add a new entry to the vault. Use SetEntryValue or SetEntryValueStr to assign a value to the new entry.

ChangeEntryKey Method (PasswordVault Component)

Changes the entry's encryption key.

Syntax

procedure ChangeEntryKey(EntryName: String; NewKey: TBytes);

Config Settings (PasswordVault 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.

PasswordVault 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.

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.

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.
