Install Seeder
Install the application from Google Play on an Android phone. For sensitive recovery-seed operations, a separate offline phone is recommended.
SEEDER APP
Download Seeder for Android.
Encrypt and decrypt your recovery seed locally on a dedicated Android phone.
ANDROID ONLY
The Seeder application is currently available
only for Android phones.
Google Play package:
com.seeder.reader
Scan with your Android phone
Opens the official Seeder page
in Google Play.
HOW TO START
The app is the offline part of Seeder.
The Seeder Android application performs the sensitive encryption and decryption operation locally on the phone. The encrypted package can then be transferred to the separate blockchain administration.
Encrypt offline
Enter your recovery seed and encryption password while the device is offline. Seeder creates the encrypted package locally.
Store encrypted data
Transfer only the encrypted package to Seeder blockchain administration for long-term storage.
INDEPENDENT RECOVERY
Your recovery does not depend only on Seeder.
Seeder uses standard cryptographic primitives. A compatible command-line implementation can decrypt a stored Seeder encrypted package without the Seeder Android application.
This is important for long-term recovery. With the encrypted package, the correct password and a compatible implementation of the Seeder package format, decryption can be performed from a computer command line using OpenSSL cryptographic APIs.
MINIMUM
OpenSSL 3.2
RECOMMENDED
OpenSSL 3.5 LTS
KEY DERIVATION
Argon2id
ENCRYPTION
AES-256-GCM
Check your OpenSSL installation
openssl version
openssl list -kdf-algorithms | grep -i argon2
Command-line recovery
OpenSSL 3.2 and newer provides the cryptographic building blocks required for an independent implementation of the Seeder format.
