Decoding Base64 Encoded Data in Solana: A Guide
As you’re new to the Solana blockchain, you’re probably familiar with WebSockets and Signatures. However, when working with base64 encoded data, things can get complicated.
In this article, we’ll take a closer look at how to decrypt base64 encoded data using Raydium Authority V4 (RV4) on Solana.
Problem: Base64 Encoding and Decoding
Base64 encoding is a widely used method for representing binary data in text format. It’s most commonly used to transmit sensitive information over networks because it allows for the compact representation of large amounts of data. However, when you receive the encrypted data on the other end, you need to decrypt it back to its original format.
Solana’s base64 encoding and decoding are handled by the “solana-base64-encoded” package, which is included in the Solana SDK. To complicate things further, we will use the „accountSubscribe” method provided by Raydium Authority V4 to subscribe to the base repository for a specific account.
Decode Base64 Encoded Data
To decrypt base64 encoded data, you can use the following method:
- Subscribe to the specified account and get the account’s base repository.
- Use the Solana SDK’s „base64::decode()” function to decode the base64 string into a buffer or Uint8Array.
- Decode the buffer or Uint8Array back to its original binary format using the „base64::decode()” function.
Here is some sample code illustrating this process:
„` rust
use raydium_authority_v4::{
account,
BaseVault,
};
use solana_sdk::pubkey::{Pubkey, PubkeyCollection};
use solana_sdk::signature::{Signature, SignaturePubkey};
use solana_sdk::transaction::TransactionId;
use solana_sdk::vec::Vec;
// Subscribe to a specific account and get the base storage
async fn subscribe_to_base_vault(
account_id: &str,
pubkey: pubkey,
) -> Output {
// Assuming you created an account object from the account id
let account = Account::from_account_id(Pubkey::from_str(account_id).unwrap());
// Get the base storage for the specified account
let vault = account.base_vault().wait;
Ok (vaulted)
}
// Subscribe to a specific account and get the base storage using RV4
async fn subscribe_to_base_vault_rv4(
account_id: &str,
pubkey: pubkey,
) -> Output {
// Assuming you created an account object from the account id
let account = Account::from_account_id(Pubkey::from_str(account_id).unwrap());
// Subscribe to a specific base repository using RV4
let base_vault_rv4 = account.base_vault_rv4().wait?;
OK (base_vault_rv4)
}
// Decode the base64 encoded data back to binary format
async fn decode_base64(data: Vec) -> Result<Vec, string> {
// Assuming you have the base64 decoder function provided by RV4
let decoded_data = base64::decode(&data).wait?;
OK (decoded_data)
}
// Example usage:
async fn main() -> Result {
// Subscribe to a specific account and get the base storage using RV4
let account_id = „your_account_id_here”;
let pubkey = Pubkey::from_str(„your_pubkey_here”).unwrap();
let base_vault_rv4 = subscribe_to_base_vault_rv4(&account_id, &public_key).wait?;
// Subscribe to a specific account and get base storage using accountSubscribe
let subscription = accountSubscribe(&base_vault_rv4.base_vault().wait, base_vault_rv4.public_key(), „your_account_id_here”, Pubkey::from_str(„your_public_key_here”).unwrap()).wait?;
let base_vault = subscription.get_last_transaction().wait?;
// Decode the base64 encoded data back to binary format
let decoded_data = decode_base64(&base_vault.data).wait?;
println!(„{:x?
