![]() This is less secure than choosing the seed or private key completely at random, but there are some rare cases where you want to do this. You can, optionally, use a passphrase or some other input as a way of choosing a seed or private key. There are some situations where you might temporarily keep a public key to yourself, but eventually you need to publish it as part of a transaction so that the XRP Ledger can verify the signature and process the transaction.įor more technical details of how key derivation works, see Key Derivation. ![]() The public key, account ID, and address are public information. If someone else can access it, they can take control of your account. If you don't have it, you can't use your account. If you own an account, be very careful with your account's secret information. The passphrase, seed, and private key are secrets: if you know any of these values for an account, you can make valid signatures and you have full control over that account. Address 24 bytes (classic) 32 bytes (X-address) Public information Secrets Account ID 20 bytes Public Key 33 bytes Private Key 32 bytes Passphrase or source of randomness (Optional) Seed (Optional) 16 bytesįigure: A simplified view of the relationship between cryptographic key values. When dealing with the XRP Ledger, you may also use some related values such as a passphrase, seed, account ID, or address. The cryptographic signing algorithm defines the key derivation process and sets constraints on the numbers that can be cryptographic keys. Each key is a number the private key should be chosen using a strong source of randomness. Key ComponentsĪ cryptographic key pair is a private key and a public key that are connected mathematically through a key derivation process. ![]() Compromised applications can expose your secret to malicious users who can then send transactions from your account later. However, you should only use key pairs that were generated with devices and software you trust. Many client libraries and applications can generate a key pair suitable for use with the XRP Ledger. If someone else knows the seed or private key of your XRP Ledger account, that person can create digital signatures to authorize any transaction the same as you could. Digital signatures are the only way of authorizing transactions in the XRP Ledger, and there is no privileged administrator who can undo or reverse any transactions after they have applied. Warning: It is important to maintain proper security over your cryptographic keys. A key pair can be used as a master key pair, regular key pair or a member of a signer list, regardless of what algorithm was used to generate it. A key pair may be generated using any of the XRP Ledger's supported cryptographic signing algorithms. To make a digital signature, you use a cryptographic key pair associated with the transaction's sending account. Only signed transactions can be submitted to the network and included in a validated ledger. I'll have to solve those first and then this problem will be solved too.In the XRP Ledger, a digital signature authorizes a transaction to do a specific set of actions. Now I realise I have a problem when reading the values from that FORM. Ok, so this works in the Serial monitor but what I really want is that the input "DE" is written to EEPROM (I can't provide "0xDE") This is because I get the value from a FORM submitted via a webpage.
