SecureString ActiveX Reference Documentation

SecureString

Current Version: 9.5.0.97

A string class that stores the characters in memory in 256-bit AES CBC encrypted form. The encryption key will be a randomly-generated key.

Object Creation

(ASP)
set obj = Server.CreateObject("Chilkat_9_5_0.SecureString")

(AutoIt)
$obj = ObjCreate("Chilkat_9_5_0.SecureString")

(Visual Basic 6.0)
Dim obj As New ChilkatSecureString

(VBScript)
set obj = CreateObject("Chilkat_9_5_0.SecureString")

(Delphi)
obj := TChilkatSecureString.Create(Self);

(FoxPro)
loObject = CreateObject('Chilkat_9_5_0.SecureString')

(PowerBuilder)
lole_object = create oleobject
li_rc = lole_object.ConnectToNewObject("Chilkat_9_5_0.SecureString")

(SQL Server)
EXEC @hr = sp_OACreate 'Chilkat_9_5_0.SecureString', @obj OUT

(Javascript)
var obj = new ActiveXObject("Chilkat_9_5_0.SecureString");

Properties

LastBinaryResult
LastBinaryResult As Variant (read-only)

The binary data returned by the last (binary data returning) method called. Only available if Chilkat.Global.KeepBinaryResult is set to 1. 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
LastMethodSuccess
LastMethodSuccess As Long

Indicate whether the last method call succeeded or failed. A value of 1 indicates success, a value of 0 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 = 1 and failure = 0.
  • 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 1. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

top
LastStringResult
LastStringResult As String (read-only)

The string return value of the last (string returning) method called. Only available if Chilkat.Global.KeepStringResult is set to 1. 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).

top
LastStringResultLen
LastStringResultLen As Long (read-only)

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

top
MaintainHash
MaintainHash As String
Introduced in version 9.5.0.71

If set to the name of a hash algorithm, then a hash of the current string value is maintained. This allows for the hash to be verified via the VerifyHash method. Possible hash algorithm names are "sha1", "sha256", "sha384", "sha512", "md5", "md2", "ripemd160", "ripemd128","ripemd256", and "ripemd320".

top
ReadOnly
ReadOnly As Long
Introduced in version 9.5.0.71

Can be set to 1 to make this secure string read-only (cannot be modified).

Methods

Access
Access() As String
Introduced in version 9.5.0.71

Returns the clear-text string value.

Returns Nothing on failure

top
Append
Append(str As String) As Long
Introduced in version 9.5.0.71

Appends a clear-text string to this secure string. The in-memory data will be decrypted, the string will be appended, and then it will be re-encrypted. Can return 0 if the string has been marked as read-only via the ReadOnly property.

Returns 1 for success, 0 for failure.

top
AppendSb
AppendSb(sb As ChilkatStringBuilder) As Long
Introduced in version 9.5.0.71

Appends a clear-text string contained in a StringBuilder to this secure string. The in-memory data will be decrypted, the string will be appended, and then it will be re-encrypted. Can return 0 if the string has been marked as read-only via the ReadOnly property.

Returns 1 for success, 0 for failure.

top
AppendSecure
AppendSecure(secStr As ChilkatSecureString) As Long
Introduced in version 9.5.0.71

Appends the contents of a secure string to this secure string. The in-memory data will be decrypted, the secure string will be appended, and then it will be re-encrypted. Can return 0 if this string has been marked as read-only via the ReadOnly property.

top
HashVal
HashVal(encoding As String) As String
Introduced in version 9.5.0.71

Returns the hash value for the current value of this secure string. The encoding specifies the encoding to be used. It can be any of the binary encoding algorithms, such as "base64", "hex", and many more listed at Chilkat Binary Encodings

Returns Nothing on failure

top
LoadFile
LoadFile(path As String, charset As String) As Long
Introduced in version 9.5.0.71

Loads the contents of a file into this secure string. The current contents of this object are replaced with the new text from the file.

Returns 1 for success, 0 for failure.

top
SecStrEquals
SecStrEquals(secStr As ChilkatSecureString) As Long
Introduced in version 9.5.0.71

Returns 1 if the secStr equals the contents of this secure string.

Returns 1 for success, 0 for failure.

top
VerifyHash
VerifyHash(hashVal As String, encoding As String) As Long
Introduced in version 9.5.0.71

Verifies the hashVal against the hash value stored for the current value of this secure string. The MaintainHash property must've previously been set for this secure string to maintain an internal hash. The encoding specifies the encoding of the hashVal. It can be any of the binary encoding algorithms, such as "base64", "hex", and many more listed at Chilkat Binary Encodings

Returns 1 for success, 0 for failure.
