Pem Xojo Plugin Reference Documentation

Pem

Current Version: 11.0.0

For creating, loading, parsing, converting, and saving in the PEM format.

Note: There are many types of objects that can be stored in PEM format. Chilkat supports certificates, private keys, and public keys. There is still much more to do. If there is a need to support a particular type of content, contact Chilkat (support@chilkatsoft.com).

Object Creation

Dim pem As New Chilkat.Pem

Properties

AppendMode
AppendMode As Boolean
Introduced in version 9.5.0.49

When set to True, each of the Load* methods appends to the current contents of this PEM object. When set to False, a Load* method replaces the contents of this PEM object. The default is False.

top
DebugLogFilePath
DebugLogFilePath As String

If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.

Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.

Possible causes of hangs include:

  • A timeout property set to 0, indicating an infinite timeout.
  • A hang occurring within an event callback in the application code.
  • An internal bug in the Chilkat code causing the hang.

HeartbeatMs
HeartbeatMs As Int32
Introduced in version 9.5.0.49

This is the number of milliseconds between each AbortCheck event callback. The AbortCheck callback allows an application to abort any event-enabled methods prior to completion. If HeartbeatMs is 0 (the default), no AbortCheck event callbacks will fire.

top
LastErrorHtml
LastErrorHtml As String (read-only)

Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastErrorText
LastErrorText As String (read-only)

Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastErrorXml
LastErrorXml As String (read-only)

Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastMethodSuccess
LastMethodSuccess As Boolean

Indicates the success or failure of the most recent method call: True means success, False means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages.

top

top
PrivateKeyFormat
PrivateKeyFormat As String
Introduced in version 9.5.0.49

Controls the format to be used for unencrypted private keys when writing a PEM. Possible values are "pkcs1" and "pkcs8". (OpenSSL typically uses the "pkcs8" format.) When writing encrypted private keys to PEM, the format is always PKCS8, and the PEM header is "BEGIN ENCRYPTED PRIVATE KEY". The default is "pkcs8".

The PKCS1 format uses the PEM header: BEGIN RSA PRIVATE KEY.
The PKCS8 format uses the PEM header: BEGIN PRIVATE KEY.

top
PublicKeyFormat
PublicKeyFormat As String
Introduced in version 9.5.0.49

Controls the format to be used for public keys when writing a PEM. Possible values are "pkcs1" and "pkcs8". (OpenSSL typically uses the "pkcs8" format.) The default is "pkcs8".

The PKCS1 format uses the PEM header: BEGIN RSA PUBLIC KEY.
The PKCS8 format uses the PEM header: BEGIN PUBLIC KEY.

More Information and Examples

VerboseLogging
VerboseLogging As Boolean

If set to True, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is False. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

ToPemEx
Function ToPemEx(extendedAttrs As Boolean, noKeys As Boolean, noCerts As Boolean, noCaCerts As Boolean, encryptAlg As String, password As String) As String
Introduced in version 9.5.0.49

Write the PFX to a PEM formatted string. If extendedAttrs is True, then extended properties (Bag Attributes and Key Attributes) are output. If noKeys is True, then no private keys are output. If noCerts is True, then no certificates are output. If noCaCerts is True, then no CA certs or intermediate CA certs are output. If encryptAlg is not empty, it indicates the encryption algorithm to be used for encrypting the private keys (otherwise the private keys are output unencrypted). The possible choices for the encryptAlg are "des3", "aes128", "aes192", and "aes256". (All encryption algorithm choices use CBC mode.) If the private keys are to be encrypted, then password is the password to be used. Otherwise, password may be left empty. For example:

Bag Attributes
    Microsoft Local Key set: <No Values>
    localKeyID: 01 00 00 00 
    friendlyName: le-2b09a3d2-9037-4a05-95cc-4d44518e8607
