JAVA eDOC Libraries integration guidelines

Overview

eDOC 2.0 is an electronic document format used in Latvia, based on:

• XAdES (XML Advanced Electronic Signatures)
• ASiC-E (Associated Signature Container)

It complies with:

• eIDAS Regulation (EU No 910/2014)
• ETSI standards for electronic signatures

Format Structure

.edoc file is a container that includes:

• One or more documents
• XAdES signature
• Timestamp (time-stamping)
• Validation data (OCSP/CRL for long-term validation)

Technical details

• Container format: ASiC-E
• Signature format: XAdES
• File extension: .edoc
• Compatible with .asice (ETSI standard)

Signature Characteristics

eDOC 2.0 signatures:

• Use XAdES standard
• Are created at LTV (Long-Term Validation) level
• Support parallel signatures

This ensures:

• Long-term validity of signatures
• Embedded certificate validation data
• Timestamp protection against future disputes

Standards

The following standards apply:

• ETSI EN 319 132 (XAdES)
• ETSI EN 319 162 (ASiC)
• ETSI EN 319 102 (signature creation & validation)
• eIDAS Regulation (EU 910/2014)

Integration Scenarios

Typical Java implementations include:

1. Document Signing

• Add document(s) to container
• Create XAdES signature
• Add timestamp
• Package as .edoc

2. Signature Validation

• Validate XAdES signature
• Validate certificate (OCSP/CRL)
• Validate timestamp
• Verify integrity of container

3. Content Extraction

• Extract documents from container
• Read metadata
• Inspect signatures
