CkAsn

The ASN.1 item's boolean value if it is a boolean item.

True if this ASN.1 item is a constructed item. Sequence and Set items are constructed and can contain sub-items. All other tags (boolean, integer, octets, utf8String, etc.) are primitive (non-constructed).

The ASN.1 item's content if it is an ASN.1 string type (such as Utf8String, BmpString, PrintableString, VisibleString, T61String, IA5String, NumericString, or UniversalString).

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.

The ASN.1 item's integer value if it is a small integer item.

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.

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.

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.

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.

The number of sub-items contained within this ASN.1 item. Only constructed items, such as Sequence and Set will contain sub-iitems. Primitive items such as OIDs, octet strings, integers, etc. will never contain sub-items.

The ASN.1 item's tag as a descriptive string. Possible values are:

boolean
integer
bitString
octets
null
oid
utf8String
relativeOid
sequence
set
numericString
printableString
t61String
ia5String
utcTime
bmpString

The ASN.1 item's tag as a integer value. The integer values for possible tags are as follows:

boolean (1)
integer (2)
bitString (3)
octets (4)
null (5)
oid (6)
utf8String (12)
relativeOid (13)
sequence (16)
set (17)
numericString (18)
printableString (19)
t61String (20)
ia5String (22)
utcTime (23)
bmpString (30)

When set to True, all "const char *" arguments are interpreted as utf-8 strings. If set to False (the default), then "const char *" arguments are interpreted as ANSI strings. Also, when set to True, and Chilkat method returning a "const char *" is returning the utf-8 representation. If set to False, all "const char *" return values are ANSI strings.

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 of the component/library, such as "9.5.0.94"

Appends an ASN.1 integer, but one that is a big (huge) integer that is too large to be represented by an integer variable. The bytes composing the integer are passed in encoded string format (such as base64, hex, etc.). The byte order must be big-endian. The encoding may be any of the following encodings: "Base64", "Hex", "Base58", "modBase64", "Base32", "UU", "QP" (for quoted-printable), "URL" (for url-encoding), "Q", "B", "url_oath", "url_rfc1738", "url_rfc2396", and "url_rfc3986". The encoding name is case insensitive (for example, both "Base64" and "base64" are treated the same).

Returns True for success, False for failure.

Appends an ASN.1 bit string to the caller's sub-items. The bytes containing the bits are passed in encoded string format (such as base64, hex, etc.). The byte order must be big-endian (MSB first). The encoding may be any of the following encodings: "Base64", "Hex", "Base58", "modBase64", "Base32", "UU", "QP" (for quoted-printable), "URL" (for url-encoding), "Q", "B", "url_oath", "url_rfc1738", "url_rfc2396", and "url_rfc3986". The encoding name is case insensitive (for example, both "Base64" and "base64" are treated the same).

Returns True for success, False for failure.

The encoding name is case insensitive (for example, both "Base64" and "base64" are treated the same).

Appends a string item to the caller's sub-items. The strType specifies the type of string to be added. It may be "utf8", "ia5", "t61", "printable", "visible", "numeric", "universal", or "bmp". The value must conform to the ASN.1 restrictions imposed for a given string type. The "utf8", "bmp", and "universal" types have no restrictions on what characters are allowed. In general, unless a specific type of string is required, choose the "utf8" type.

Returns True for success, False for failure.

Appends a UTCTime item to the caller's sub-items. The timeFormat specifies the format of the dateTimeStr. It should be set to "utc". (In the future, this method will be expanded to append GeneralizedTime items by using "generalized" for timeFormat.) To append the current date/time, set dateTimeStr equal to the empty string or the keyword "now". Otherwise, the dateTimeStr should be in the UTC time format "YYMMDDhhmm[ss]Z" or "YYMMDDhhmm[ss](+|-)hhmm".
