SshKey PHP ActiveX Reference Documentation

SshKey

Current Version: 10.0.0
Requires Chilkat Bundle License

Provides the ability to read and write Putty and OpenSSH format public and private keys. Supports both DSA and RSA keys. Able to generate new keys. Encryption/decryption of keys is supported. Can convert to/from Putty OpenSSH, and XML formats.

Object Creation

Chilkat v10.0.0 or greater:
$obj = new COM("Chilkat.SshKey");
Chilkat v9.5.0.*:
$obj = new COM("Chilkat_9_5_0.SshKey");

Properties

Comment
string Comment

Some key file formats allow a comment to be included. This is the comment if present.

top
DebugLogFilePath
string DebugLogFilePath

If set to a file path, causes each Chilkat method or property call to automatically append it's LastErrorText to the specified log file. The information is appended such that if a hang or crash occurs, it is possible to see the context in which the problem occurred, as well as a history of all Chilkat calls up to the point of the problem. The VerboseLogging property can be set to provide more detailed information.

This property is typically used for debugging the rare cases where a Chilkat method call hangs or generates an exception that halts program execution (i.e. crashes). A hang or crash should generally never happen. The typical causes of a hang are:

  1. a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
  2. the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
  3. there is an internal problem (bug) in the Chilkat code that causes the hang.

More Information and Examples
Example showing how to use DebugLogFilePath.
top
IsDsaKey
bool IsDsaKey (read-only)

true if the object contains a DSA key. false if the object contains an RSA key.

top
IsPrivateKey
bool IsPrivateKey (read-only)

true if the object contains a private key. false if it contains a public key.

top
IsRsaKey
bool IsRsaKey (read-only)

true if the object contains an RSA key. false if the object contains a DSA key.

top
KeyType
string KeyType (read-only)
Introduced in version 9.5.0.83

Indicates the type of key held in this object instance. Can be "rsa", "dsa", "ecdsa", "ed25519", or "none".

top
LastBinaryResult
VARIANT LastBinaryResult (read-only)

The binary data returned by the last (binary data returning) method called. Only available if Chilkat.Global.KeepBinaryResult is set to true. This provides a means for obtaining large varbinary results in the SQL Server environment (where limitations exist in getting large amounts of data returned by method calls, but where temp tables can be used for binary properties).

top
LastErrorHtml
string LastErrorHtml (read-only)

Provides information in HTML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorText
string LastErrorText (read-only)

Provides information in plain-text format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

More Information and Examples
Concept of LastErrorTextLastErrorText Standard Information
top
LastErrorXml
string LastErrorXml (read-only)

Provides information in XML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastMethodSuccess
bool LastMethodSuccess

Indicate whether the last method call succeeded or failed. A value of true indicates success, a value of false indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:

  • Any method that returns a string.
  • Any method returning a Chilkat object, binary bytes, or a date/time.
  • Any method returning a standard boolean status value where success = true and failure = false.
  • Any method returning an integer where failure is defined by a return value less than zero.

Note: Methods that do not fit the above requirements will always set this property equal to true. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

top
LastStringResult
string LastStringResult (read-only)

The string return value of the last (string returning) method called. Only available if Chilkat.Global.KeepStringResult is set to true. This provides a means for obtaining large string results in the SQL Server environment (where limitations exist in getting long strings returned by method calls, but where temp tables can be used for string properties).

More Information and Examples
Long Strings Returned by ActiveX Methods in SQL Server
top
LastStringResultLen
int LastStringResultLen (read-only)

The length, in characters, of the string contained in the LastStringResult property.

top
Password
string Password

The password to be used when importing or exporting encrypted private keys. If the private key is in an unencrypted format, the password is ignored.

More Information and Examples
Use PuTTY Key for SSH Tunnel (PPK Private Key)
top
UncommonOptions
string UncommonOptions

This is a catch-all property to be used for uncommon needs. This property defaults to the empty string, and should typically remain empty.

Can be set to a list of the following comma separated keywords:

  • "DES-EDE3-CBC" - Use older Triple-DES encryption (instead of the default AES-128-CBC) when creating encrypted OpenSSH private keys.

top
VerboseLogging
bool VerboseLogging

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.

top
Version
string Version (read-only)

Version of the component/library, such as "9.5.0.94"

More Information and Examples
How to get the Chilkat version at runtime.

Methods

FromOpenSshPrivateKey
bool FromOpenSshPrivateKey(string keyStr)

Loads an SSH key from an OpenSSH private-key file format. If the key is encrypted, set the Password property prior to calling this method.

Note: keyStr is not a filename -- it should contain the contents of the OpenSSH formatted private key. To load from a file, you may first call LoadText to load the complete contents of a text file into a string.

Here are are samples of RSA and DSA private keys in OpenSSH format, both encrypted and unencrypted:

FromXml
bool FromXml(string xmlKey)

Loads an SSH key from XML.

Note: xmlKey is not a filename -- it should contain the contents of the XML SSH key. To load from a file, you may first call LoadText to load the complete contents of a text file into a string.

Here are RSA public/private keys in XML format:

GenerateDsaKey
bool GenerateDsaKey(int numBits)

Generates a new SSH DSA key that is numBits bits in length. The numBits should be at least 1024 bits and a multiple of 64. Typical values are 1024 and 2048.

Returns true for success, false for failure.

More Information and Examples

top
GenerateEcdsaKey
bool GenerateEcdsaKey(string curveName)
Introduced in version 9.5.0.83

Generates an ECDSA (ECC) private key. The curveName specifies the curve name which determines the key size.

The following curve names are accepted:

  • secp256r1 (also known as P-256 and prime256v1)
  • secp384r1 (also known as P-384)
  • secp521r1 (also known as P-521)

Returns true for success, false for failure.

top
GenerateEd25519Key
bool GenerateEd25519Key()
Introduced in version 9.5.0.83

Generates a new ED25519 public/private key pair.

Returns true for success, false for failure.

More Information and Examples
Generate ed25519 Key and Save to PuTTY Format
top
GenerateRsaKey
bool GenerateRsaKey(int numBits, int exponent)

Generates a new RSA public/private key pair. The numBits can range from 384 to 4096. Typical key lengths are 1024 or 2048 bits. After successful generation, the public/private keys can be exported in OpenSSH or PuTTY format.

(excerpt from Wikipedia's article on RSA) 65537 is a commonly used value for exponent. This value can be regarded as a compromise between avoiding potential small exponent attacks and still allowing efficient encryptions (or signature verification). The NIST Special Publication on Computer Security (SP 800-78 Rev 1 of August 2007) does not allow public exponents e smaller than 65537, but does not state a reason for this restriction.

Returns true for success, false for failure.
