All editions allow to decode and modify values using BER, DER, PER (aligned and unaligned) and XER (basic and canonical) encoding rules. All precompiled/ready-to-use standard ASN.1 descriptions can be used.
The Professional Edition has no limitations. Files having several thousands and millions of values, like CDR files, can be created, decoded, modified and encoded.
The Basic Edition allows to process only one value. If a file contains more than one value, only the first value is decoded. The ASN.1 value can then be modified and encoded. The ASN.1 value creation is also limited to one value. TAP3 decoding and encoding is not available in the Basic Edition.
The Free Trial is time-limited and does not offer all the capabilities of the standard product. Only the first 10 values of an ASN.1 encoded file are decoded. Encoding is not possible, it is available in the Basic or Professional Edition.
