Technical specifications

Protection modes

Password mode : Perfect for occasional exchanges. Protect your documents with a password that you securely transmit to your recipient.
Certificate mode : Ideal for teams and regular exchanges. Use X509 certificates for enhanced security and simplified access management.

Algorithms and methods

Encryption algorithms: AES-GCM 256-bit with AAD or ChaCha20-Poly1305
Key derivation: PBKDF2 or Argon2 for password mode
Certificate protection: Asymmetric encryption of session keys

Timestamping

Proof format: RFC 3161 timestamp token or ASiC-S container (ETSI EN 319 162)
Authority certificate identification: ESSCertIDv2 (RFC 5816)
Supported digest algorithms: SHA-256 / SHA-384 / SHA-512
Levels: Sigalion timestamping or qualified eIDAS ETSI EN 319 421
Verification: checks the signature and the authority's certification chain

Electronic signature

Signature format: CAdES baseline-T (ETSI EN 319 122-1), detached CMS (RFC 5652) in an ASiC-S container
Embedded timestamp: RFC 3161 token on the signature value (level -T), Sigalion or eIDAS qualified
Certificate media: software certificate, smart card or token (IDOpte, YubiKey) on macOS, Windows and Linux
Verification: trusted authorities and eIDAS qualification taken from the national Trusted Lists of seven European countries (France, Belgium, Netherlands, Italy, Spain, Portugal, Austria), revocation of the signer and of its issuer checked at the signing date attested by the timestamp

Secure transfer

Transfer plans: Free Plan (3 active files, 5 MB/file, 7-day history) or Giga Plan (50 files up to 1 GB total, 100 MB/file, 30-day history).
Unique temporary link: Share your files via a secure link with automatic expiration (48h on Free, 7 days on Giga).
