Generate a Seed

EXPLANATION: Seeds

You can learn more about seeds in the Explanations Section.

Avoid Seed Generators

Please note, it is highly recommended that you avoid using online seed generators. The seed is the only key to the given addresses. So, anyone who owns the seed also owns all the funds related to respective IOTA addresses.

Java

You can generate a seed, for example, using the SHA256 algorithm on some random input generated by a cryptographically secure pseudo-random generator, such as SecretKey.generate():

Nodejs

You can generate a seed, for example, using the SHA256 algorithm on some random input generated by a cryptographically secure pseudo-random generator, such as crypto.randomBytes():

info

Though it is possible to send transactions with iota.rs, we strongly recommend that you use the official wallet.rs library together with the stronghold.rs enclave for value-based transfers. This combination incorporates the best security practices while dealing with seeds, related addresses, and UTXO.
