Use this method to save the key (both the public and secret parts) to the file specified in Filename.

generate_pair Method

Generates a new pair of PGP keys.

Syntax

def generate_pair(version: int, username: str, strength: int, valid_to: str, password: str) -> None: ...

Remarks

ToDo Use this method to create a new key-subkey pair. This is the primary method for generating conformant PGP keys.

Pass the user ID of the new key via the Username property. This typically should be in the format of User Name <user@email>, for example Robert Frost <robert@frost.com>, but generally can be an arbitrary text string.

Set KeyAlgorithm and SubKeyAlgorithm to the public key algorithms that you want to use for the new key. See the full list of algorithms below. Where ECDSA or ECDH algorithm is used, you can specify a particular curve after the algorithm name, separated with the colon: ECDSA:P384 or ECDH:BRAINPOOLP256. KeyBits and SubKeyBits specify the number of bits in the key and the subkey. These parameters can be set to zero if the key length is implicitly defined by the algorithm of the key. For example, ECDSA P256 keys are always 256 bit long, so you may pass 0 as the corresponding KeyBits or SubKeyBits parameter.

Provide the key encryption password and the validity period in days via the Password and Expires parameters. Set Expires to zero to indicate that the key does not expire.

While you can use any combination of algorithms for your key and subkey, most implementations got used to specific hard-wired combinations. Sticking to those will help make sure your keys are understood by other implementations. Typical combinations are:

EDDSA main key with ECDH:CURVE25519 subkey;
ECDSA main key with ECDH subkey; both with NIST curves (P256, P384, or P512);
ECDSA main key with ECDH subkey; both with Brainpool curves (BRAINPOOLP256 or BRAINPOOLP512);
RSA main key with RSA subkey.

The code snippet below illustrates a typical key generation procedure:

    Pgpkeymanager mgr = new Pgpkeymanager();

    // generating a pair
    mgr.GeneratePair("Michel Legrand <ml@email.com>", "EDDSA", 0, "ECDH:CURVE25519", 0, "password", 0);

    // creating a keyring object and adding the new pair to the keyring
    Pgpkeyring keyring = new Pgpkeyring();

    keyring.CreateNew();

    keyring.PinnedKey = mgr.Key;
    keyring.AddPinned();

    // exporting the keyring to a file
    keyring.Save("pubkey.pkr", "seckey.skr");

Alternative calls to GeneratePair may look like this:

    mgr.GeneratePair("Michel Legrand <ml@email.com>", "ECDSA:P384", 0, "ECDH", 0, "password", 0);

    mgr.GeneratePair("Michel Legrand <ml@email.com>", "ECDSA:BRAINPOOLP256", 0, "ECDH:BRAINPOOLP256", 0, "password", 0);

    mgr.GeneratePair("Michel Legrand <ml@email.com>", "RSA", 4096, "RSA", 2048, "password", 0);

include-module		Include a module specified in the value
include-class		Include a class specified in the value
include-method		Include 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:


none		No flush (caching only)
immediate		Immediate flush (real-time logging)
maxcount		Flush 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:


none		None (by default)
fatal		Severe errors that cause premature termination.
error		Other runtime errors or unexpected conditions.
warning		Use of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong".
info		Interesting runtime events (startup/shutdown).
debug		Detailed information on flow of through the system.
trace		More 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:


none		No rotation
deleteolder		Delete older entries from the cache upon reaching LogMaxEventCount
keepolder		Keep 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 class. Works only if UseOwnDNSResolver is set to true.

Supported values are:


none		No static DNS rules (default)
local		Local static DNS rules
global		Global 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 class) 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 class is set to "local", the property returns/restores the rules from/to the internal storage of the class. If StaticDNS of the class 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 classes.

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.
