Problem when constructing ContractIds containing colons ":"

[paullatzelsperger]

Bug Report

Describe the Bug

Having Assets where the id contains the ":" colon character causes problems during contract negotiation, causing the negotiation instance not to be found.

Expected Behavior

(see link below)

Observed Behavior

(see link below)

Steps to Reproduce, Context Information

eclipse-tractusx/tractusx-edc#484

Detailed Description

ContractId instances are constructed in the form <CONTRACT_DEF_ID>:<ASSET_ID>:<UUID> using ":" as delimiter character and are parsed accordingly. If either the contract definition id or the asset id contains a colon ":" character, that would throw off the parsing algorithm.

Possible Implementations

• make the delimiter configurable, default to ":"
• make ContractIds opaque, e.g. base64 encode the parts (<-- probably the best solution)

I also agree on making the ContractId parts opaque with encoding, at that point we could remove the : validation on ContractDefinition. I can take care of this
