BlockchainSign is a blockchain timestamping service for people holding documents they cannot hand over.

Conventional options all require custody: a copyright office wants a deposit copy, a notary wants to see the paper, an e-signature platform wants the file on its servers. BlockchainSign never receives the file at all. The document is hashed with SHA-256 in the user's own browser using the Web Crypto API, and only the resulting hash is written to the Ethereum blockchain.

The result is a certificate file recording the hash, the transaction and the timestamp. Because each certificate is its own Ethereum L1 transaction, with the payload hash readable as UTF-8 on a public block explorer, verification does not run through the vendor's portal: if BlockchainSign shut down, existing certificates would still verify.

There is no subscription and no cryptocurrency wallet involved. Certificates are bought as credits with a card and spent when needed. Credits are valid for 12 months; an issued certificate never expires.

Key points

  • The file is never uploaded โ€” only its SHA-256 hash is transmitted
  • Recorded on Ethereum L1, one transaction per certificate
  • Verifiable on a public block explorer, independently of us
  • No subscription, no renewal, no wallet, no crypto knowledge needed
  • A free SHA-256 file hash generator is available with no account
  • Available in English, French, German, Spanish and Portuguese

What it does not do. A timestamp proves that a file existed in that exact form at that time โ€” existence and integrity. It does not prove authorship or ownership, and it is not a substitute for copyright registration. There is no API or integrations yet, and no eIDAS qualified timestamp.

AES Crypt features and specs

  • Strong Encryption
    AES Crypt uses the Advanced Encryption Standard (AES), which is known for its high level of security and efficiency.
  • Cross-Platform
    AES Crypt is available for Windows, macOS, Linux, and Android, making it versatile and accessible across different operating systems.
  • Open Source
    The software is open source, allowing users to review the code for security vulnerabilities and ensure transparency.
  • Ease of Use
    AES Crypt offers a simple, user-friendly interface, making it accessible even to those who are not technically inclined.
  • No Cost
    AES Crypt is free to download and use, making it an economical choice for secure file encryption.

Possible disadvantages of AES Crypt

  • Limited Features
    AES Crypt focuses primarily on file encryption and lacks additional features such as folder encryption, password management, or cloud integration.
  • Manual Key Management
    Users have to manually handle encryption keys, which could be inconvenient and potentially less secure if not managed properly.
  • No Native Mobile Support
    While an Android version exists, there is no native iOS application, limiting usability for iPhone and iPad users.
  • No Integrated Key Recovery
    There is no built-in key recovery or backup feature, so if a user loses their key, their encrypted data may be irretrievable.
  • Potential for User Error
    Given that the process involves manual steps such as key management, there is a risk of user error, which could compromise security.

BlockchainSign features and specs

  • Blockchain-Based Security
    Utilizes blockchain technology to timestamp and verify document signatures, creating an immutable record that can enhance trust and reduce the risk of tampering or fraud.
  • Decentralized Verification
    Signature verification does not rely on a single centralized authority, which can increase transparency and allow independent verification of document authenticity.
  • Cost-Effective for Digital Signing
    Blockchain-based signing solutions like this often provide competitive pricing compared to traditional e-signature platforms, especially for high-volume users.
  • Tamper-Evident Records
    Once a document is signed and recorded on the blockchain, any attempt to alter it becomes detectable, providing strong evidence of document integrity over time.
  • Global Accessibility
    As a web-based platform, it can be accessed from anywhere with an internet connection, making it convenient for international business transactions and remote signing needs.

5 Best TrueCrypt Alternatives - Open source encryption apps
AES Crypt is a free open source (FOSS) cross-platform per-file encryption app which secures files using the AES-256 cipher. As a per-file encryption app, it allows you to manual encrypt individual files. Batch file encryption is not supported, although this limitation can be overcome somewhat by creating zip files out of folders, and then encrypting the zip file with AES Crypt.
