ASN.1 is a data type declaration notation. It does not define how to manipulate a variable of such a type. Manipulation of variables is defined in other languages such as SDL (Specification and Description Language) for executable modeling or TTCN-3 (Testing and Test Control Notation) for conformance testing.
X.690. X.690 is an ITU-T standard specifying several ASN.1 encoding formats: The Basic Encoding Rules (BER) were the original rules laid out by the ASN.1 standard for encoding data into a binary format. The rules, collectively referred to as a transfer syntax in ASN.1 parlance, specify the exact octets (8-bit bytes) used to encode data.
The Encoding Control Notation (ECN) is a standardized formal language that is part of the Abstract Syntax Notation One (ASN.1) family of international standards. ECN is designed to be used along with ASN.1, and each ECN specification (a coherent set of encoding definitions) is explicitly related to a particular ASN.1 specification (a coherent set of type definitions).
The PKCS#10 standard defines a binary format for encoding CSRs for use with X.509. It is expressed in ASN.1. Here is an example of how you can examine its ASN.1 structure using OpenSSL: openssl asn1parse -i -in your_request.p10. A CSR may be represented as a Base64 encoded PKCS#10; an example of which is given below:
GeneralizedTime. A GeneralizedTime is a time format in the ASN.1 notation . It consists of a string value representing the calendar date, as defined in ISO 8601, a time of day with an optional fractional seconds element and the optional local time differential factor as defined in ISO 8601.
Information Object Class (ASN.1) ASN.1 Information Object Class is a concept widely used in ASN.1 specifications to address issues related to protocol specification similar to issues addressed by CORBA/IDL specifications. Information Object Classes are used for example to specify ROSE (Remote Operations Service Element) protocol in ASN.1.
Information technology – Generic applications of ASN.1: Fast infoset: Published (2007) Specifies a representation of an instance of the W3C XML Information Set using binary encodings. These binary encodings are specified using the ASN.1 notation and the ASN.1 Encoding Control Notation (ECN). First part of the ISO/IEC 24824 series, which ...
Fast Infoset is a higher level format built on ASN.1 forms and notation. Element and attribute names are stored within the octet stream, unlike traditional ASN.1 encoding schemes. In consequence, The conventional XML file can be recovered from the binary stream without reference the XML Schema, and the XML Schema need not be expressed as an ASN ...
