ASN1
Module Implementation: OpenSSLCryptoInterfaceASN1
This module wraps various data structures defined in ASN1 (Abstract Syntax Notation One).
Note: Internal classes are italicized and will only contain a short description.
ASN1 Types

This class represents the ASN1 String built-in type.
Class methods: Creation
createNew
Create a new ASN1 Integer instance.
Answers:
<OSSslAsn1Integer> - new instance
createNewFromBytes: aByteObject
Answer a new ASN1 string from aByteObject.
The argument must be one that converts to bytes in a platform function.
Arguments:
aByteObject - @see implementors of isOpenSSLByteObject for types

<OSSslAsn1String> - new instance
createNewFromBytes: anOSObjectOrByteArray length: length
Answer a new ASN1 string from anOSObjectOrByteArray.
The argument must be one that converts to bytes in a platform
function.
Arguments:
anOSObjectOrByteArray - <ByteArray> or byte type <OSObject>
length - <Integer> set up to @length amount from the @anOSObjectOrByteArray
Answers:
<OSsslAsn1String> - new instance
createNewFromType: type
Create the new instance of the the ASN1 String of the given type.
See V_ASN1_* types in SciSslConstants pool dictionary for types.
Answers:
<OSSslAsn1String> - new instance
Instance methods: Comparison
compare: anASN1String
Answer the comparison value (semantics described in OSSslStructure>>compare:)
Answers:
<Integer>
Instance methods: Conversion
asByteArray
Convert the ASN1 String to a Smalltalk Byte Array
Answers:
<ByteArray> - byte representation
asBytes
Convert the ASN1 String to a Smalltalk Byte Array
Answers:
<ByteArray> - byte representation
asOpenSSLAsn1String
Answer a new Smalltalk object reference
to the same ASN1_STRING memory.
This object will NOT own the memory
Answers:
< OSSslAsn1String>
asString
Converts this ASN1 String into a Smalltalk String.
Answers:
<String>
Instance methods: Duplication
duplicate
Answers a managed duplicate of this ASN1 String.
Answers:
<OSSslAsn1String> - new duplicate instance
OSSslAsn1Time
This class represents the ASN1 Generalized and UTC time types. Internally, this time is stored in UTC but has conversion routines to convert to generalized time. This class also has conversion routines for Smalltalk's DateAndTime.
Class methods: Creation
createNew
Create the new instance of the the ASN1_TIME object. This will be UTC time.
Answers:
< OSSslAsn1Time> - new instance of type V_ASN1_UTCTIME
createNewFromDateAndTime: aDateAndTime
Create a new instance of the ASN1_TIME object from the Smalltalk <DateAndTime> object (which is converted to UTC).
Arguments:
aDateAndTime - <DateAndTime>
Answers:
<OSSslAsn1Time> - new instance with value set from arg
createNewFromString: aUTCFormattedString
Create a new instance of the ASN1_TIME object from the Smalltalk <String> object which described a UTC formatted time.
Arguments:
aUTCFormattedString - <String>
Answers:
<OSSslAsn1Time> - new instance with value set from arg
Instance methods: API
isValid
Validation check on the ASN1 Time object
Answers:
<Boolean> - true if valid, false otherwise.
setDateAndTime: aDateAndTime
Set the ASN1_TIME formatted date time derived from the Smalltalk <DateAndTime> object converted
to UTC.
Arguments:
aDateAndTime - <DateAndTime> converted to UTC
Answers:
<Integer> - 1 on success, otherwise an error object
Instance methods: Conversion
asDateAndTime
Answer a new UTC <DateAndTime> object from this ASN1_TIME
Answers:
<DateAndTime> - utc
asDateAndTimeLocal
Answer a new Local <DateAndTime> object from this ASN1_TIME
