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.

Cloudfogger features and specs

  • File-Level Encryption
    Cloudfogger provides file-level encryption, ensuring that individual files are protected, regardless of where they are stored or how they are transferred.
  • Cross-Platform Availability
    The service supports multiple platforms including Windows, macOS, iOS, and Android, making it versatile and accessible from a variety of devices.
  • Ease of Use
    Cloudfogger offers a user-friendly interface which simplifies the encryption process, even for users who may not be tech-savvy.
  • Compatibility with Popular Cloud Services
    The service integrates smoothly with many popular cloud storage providers such as Dropbox, Google Drive, and OneDrive, adding an extra layer of security to these services.
  • Free Basic Version
    Cloudfogger provides a free version with basic features, making encryption accessible to users who may not want to invest in a premium service.

Possible disadvantages of Cloudfogger

  • Discontinued Development
    As of my knowledge cutoff in 2021, Cloudfogger has discontinued active development and updates, which could pose security risks over time as new vulnerabilities remain unpatched.
  • No Support for Linux
    Cloudfogger does not offer a client for Linux operating systems, limiting its usability for users who rely on this OS.
  • Limited Features in Free Version
    The free version of Cloudfogger comes with limitations on advanced features, which might necessitate a premium account for full functionality.
  • Dependency on Cloudfoggerโ€™s Ecosystem
    Files that are encrypted using Cloudfogger can only be decrypted using its software, which could be a problem if the service were to shut down completely.
  • Performance Overhead
    Encrypting and decrypting files can introduce a performance overhead, potentially slowing down operations especially for large files or slower devices.

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.

Analysis of Cloudfogger

Overall verdict

  • Cloudfogger was a reputable option for those needing file encryption for cloud storage. However, as of now, the service has been discontinued, and its software is no longer supported or available. Therefore, while Cloudfogger was a good option in its time, it is not suitable for use today given the lack of updates and support.

Why this product is good

  • Cloudfogger was a tool used to encrypt files for cloud storage services like Dropbox, Google Drive, and others. It was appreciated for its ease of use and ability to encrypt files locally before uploading, ensuring that only encrypted files were stored in the cloud. This approach provided an additional layer of security for users concerned about privacy and unauthorized access to their cloud-stored data.

Recommended for

    For those seeking active alternatives, it's recommended to look into other encryption services like Boxcryptor, Cryptomator, or services built into modern cloud storage options that provide similar encryption features. These alternatives offer up-to-date support and continued development, ensuring better security and compatibility with current systems.
