AuthAzureSAS
Current Version: 10.0.0
Provides general functionality for Azure Shared Access Signature (SAS) Authorization.
This class is introduced in Chilkat v9.5.0.65.

Properties
AccessKey
This is the signing key (access key) that must be kept private. It is a base64 string such as "abdTvCZFFoWUyre6erlNN+IOb9qhXgDsyhrxmZvpmxqFDwpl9oD0X9Fy0hIQa6L5UohznRLmkCtUYySO4Y2eaw=="
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:
- a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
- the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
- there is an internal problem (bug) in the Chilkat code that causes the hang.
LastErrorHtml
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.
topLastErrorText
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.
LastErrorXml
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.
topLastMethodSuccess
Indicate whether the last method call succeeded or failed. A value of .T. indicates success, a value of .F. 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 = .T. and failure = .F..
- 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 .T.. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.
topStringToSign
Defines the format of the string to sign.
The format is specified as a comma-separated list of names. For example:
signedpermissions,signedstart,signedexpiry,canonicalizedresource,signedidentifier,signedIP,signedProtocol,signedversion,rscc,rscd,rsce,rscl,rsctThis will result in an actual string-to-sign that is composed of the values for each name separated by newline (LF) chars. For example:
signedpermissions + "\n" + signedstart + "\n" + signedexpiry + "\n" + canonicalizedresource + "\n" + signedidentifier + "\n" + signedIP + "\n" + signedProtocol + "\n" + signedversion + "\n" + rscc + "\n" + rscd + "\n" + rsce + "\n" + rscl + "\n" + rscttop
VerboseLogging
If set to .T., then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is .F.. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.
topVersion
Methods
Clear
Clears all params set by the methods SetNonTokenParam and SetTokenParam.
Returns .T. for success, .F. for failure.
topGenerateToken
Generates and returns the SAS token based on the defined StringToSign and params.
Returns .F. on failure
SetNonTokenParam
Adds a non-token parameter name/value. This is a value that is included in the string to sign, but is NOT included as a parameter in the Authorization header.
Returns .T. for success, .F. for failure.
topSetTokenParam
Adds a token parameter name/value. This is a value that is included in the string to sign, and is also included as a parameter in the Authorization header.
Returns .T. for success, .F. for failure.
