SecureString C++ Reference Documentation

CkSecureString

Current Version: 11.0.0

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

// Local variable on the stack
CkSecureString obj;

// Dynamically allocate/delete
CkSecureString *pObj = new CkSecureString();
// ...
delete pObj;

Properties

DebugLogFilePath

void get_DebugLogFilePath(CkString &str);
const char *debugLogFilePath(void);
void put_DebugLogFilePath(const char *ansiOrUtf8Str);

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.

More Information and Examples

LastErrorHtml

void get_LastErrorHtml(CkString &str);
const char *lastErrorHtml(void);

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.

LastErrorText

void get_LastErrorText(CkString &str);
const char *lastErrorText(void);

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.

LastErrorXml

void get_LastErrorXml(CkString &str);
const char *lastErrorXml(void);

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.

LastMethodSuccess

bool get_LastMethodSuccess(void);
void put_LastMethodSuccess(bool newVal);

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.

MaintainHash

void get_MaintainHash(CkString &str);
const char *maintainHash(void);
void put_MaintainHash(const char *ansiOrUtf8Str);

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".

ReadOnly

bool get_ReadOnly(void);
void put_ReadOnly(bool newVal);

Introduced in version 9.5.0.71

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

Utf8

bool get_Utf8(void);
void put_Utf8(bool newVal);

When set to true, all const char * arguments and return values are interpreted as UTF-8 strings. When set to false, they are interpreted as ANSI strings.

In Chilkat v11.0.0 and later, the default value is true. Before v11.0.0, it was false.

VerboseLogging

bool get_VerboseLogging(void);
void put_VerboseLogging(bool newVal);

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.

Version

void get_Version(CkString &str);
const char *version(void);

Version of the component/library, such as "10.1.0"

Methods

Access

bool Access(CkString &outStr);
const char *access(void);

Introduced in version 9.5.0.71

Returns the clear-text string value.

Returns true for success, false for failure.

Append

bool Append(const char *str);

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 false if the string has been marked as read-only via the ReadOnly property.

Returns true for success, false for failure.

AppendSb

bool AppendSb(CkStringBuilder &sb);

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 false if the string has been marked as read-only via the ReadOnly property.

Returns true for success, false for failure.

AppendSecure

bool AppendSecure(CkSecureString &secStr);

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 false if this string has been marked as read-only via the ReadOnly property.

HashVal

bool HashVal(const char *encoding, CkString &outStr);
const char *hashVal(const char *encoding);

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 true for success, false for failure.

LoadFile

bool LoadFile(const char *path, const char *charset);

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 true for success, false for failure.

SecStrEquals

bool SecStrEquals(CkSecureString &secStr);

Introduced in version 9.5.0.71

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

Returns true for success, false for failure.

VerifyHash

bool VerifyHash(const char *hashVal, const char *encoding);

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 true for success, false for failure.
