Allkirjades

Allkirjades is an Estonian word form related to allkirjad (signatures) and is commonly encountered in phrases referring to signatures on documents. Signatures, or allkirjad, are marks or electronic affirmations that indicate a person’s consent, authorship, or verification on a document. They can be handwritten or electronic and serve to authenticate a claim, confirm agreement, or authorize an action.

Handwritten signatures are produced by a person’s unique signing pattern and are widely used to validate contracts, letters, forms, and other records. Their reliability depends on the signer’s identity, the document’s integrity, and the potential for forgery or imitation. In contrast, electronic signatures rely on digital methods to prove consent and identity.

Under the European Union eIDAS framework, electronic signatures are categorized as simple, advanced, or qualified. A qualified electronic signature has the same legal effect as a handwritten one in EU member states. In Estonia, digital identity cards and cryptographic certificates enable widespread use of digital signatures, supported by public-key infrastructure and trusted authorities. Digital signatures provide verification of the signer’s identity, data integrity, and non-repudiation.

Verification typically involves confirming the signer’s identity, the validity of the signing certificate, and any timestamp or audit trail. For sensitive or official documents, additional steps may include notarial oversight or secure archival processes.

Historically, signatures evolved from seals and marks to modern legal instruments. In the digital era, cryptographic signatures have become standard tools for ensuring authenticity and consent in electronic commerce, administration, and governance.
