CkSecureString Java Reference Documentation

CkSecureString

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

CkSecureString obj = new CkSecureString();

Properties

LastMethodSuccess
boolean get_LastMethodSuccess();
void put_LastMethodSuccess(boolean newVal);

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.

MaintainHash
void get_MaintainHash(CkString str);
String maintainHash();
void put_MaintainHash(String newVal);
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
boolean get_ReadOnly();
void put_ReadOnly(boolean newVal);
Introduced in version 9.5.0.71

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

Methods

Access
boolean Access(CkString outStr);
String access();
Introduced in version 9.5.0.71

Returns the clear-text string value.

Returns true for success, false for failure.

top
Append
boolean Append(String 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.

top
AppendSb
boolean 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.

top
AppendSecure
boolean 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.

top
HashVal
boolean HashVal(String encoding, CkString outStr);
String hashVal(String 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.

top
LoadFile
boolean LoadFile(String path, String 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.

top
SecStrEquals
boolean 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.

top
VerifyHash
boolean VerifyHash(String hashVal, String 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.
