OSS ASN.1 tools now support an ASN.1 value notation feature. The representation structures/objects can be encoded into value notation format and those values can then be decoded to the representation structures/classes.
This feature is very useful for testing your application. The test messages can be kept in a human readable value notation format. You can parse the value notation into the representation structures/objects, serialize representation structures/objects into value notation format, and convert them to any ASN.1 binary (e.g. BER, PER, OER), JSON, or XML encoding format. It is also important to note that even though ASN.1 value notation is human readable, it is less verbose than XML and JSON, and thus more suitable for creating test messages.
The feature is also useful for creating eUICC profiles. The user can create the profile in value notation format and then use the OSS ASN.1 encoder to convert it to DER format.
The sample messages in the standards are usually in value notation format. Such messages can be easily checked, modified, and converted to any standard ASN.1 encoding format.
The feature is currently available in the time-optimized runtime of the OSS ASN.1 C, C++, Java, and C# tools. You can find details of the feature in the online documentation. A free evaluation is available here. If you have questions about value notation support in the OSS ASN.1 tools, please contact technical support at support@oss.com.
