Example - Secure Sign and Upload File to ShdwDrive using API
This example demonstrates how to securely upload files to the ShdwDrive using the provided API. It includes the process of hashing file names, creating a signed message, and sending the files along with the necessary information to the ShdwDrive endpoint.
import bs58 from 'bs58'
import nacl from 'tweetnacl'
import crypto from 'crypto'
// `files` is an array of each file passed in.
const allFileNames = files.map(file => file.fileName)
const hashSum = crypto.createHash("sha256")
// `allFileNames.toString()` creates a comma-separated list of all the file names.
const hashedFileNames = hashSum.update(allFileNames.toString())
const fileNamesHashed = hashSum.digest("hex")
// `storageAccount` is the string representation of a storage account pubkey
let msg = `Shadow Drive Signed Message:\nStorage Account: ${storageAccount}\nUpload files with hash: ${fileNamesHashed}`;
const fd = new FormData();
// `files` is an array of each file passed in
for (let j = 0; j < files.length; j++) {
fd.append("file", files[j].data, {
contentType: files[j].contentType as string,
filename: files[j].fileName,
});
}
// Expect the final message string to look something like this if you were to output it
// ShdwDrive Signed Message:
// Storage Acount: ABC123
// Upload files with hash: hash1
// If the message is not formatted like above exactly, it will fail message signature verification
// on the ShdwDrive Network side.
const encodedMessage = new TextEncoder().encode(message);
// Uses https://github.com/dchest/tweetnacl-js to sign the message. If it's not signed in the same manor,
// the message will fail signature verification on the ShdwNetwork side.
// This will return a base58 byte array of the signature.
const signedMessage = nacl.sign.detached(encodedMessage, keypair.secretKey);
// Convert the byte array to a bs58-encoded string
const signature = bs58.encode(signedMessage)
fd.append("message", signature);
fd.append("signer", keypair.publicKey.toString());
fd.append("storage_account", storageAccount.toString());
fd.append("fileNames", allFileNames.toString());
const request = await fetch(`${SHDW_DRIVE_ENDPOINT}/upload`, {
method: "POST",
body: fd,
});
Example - Editing a File in ShdwDrive using API and Message Signature Verification
In this example, we demonstrate how to edit a file in ShdwDrive using the API and message signature verification. The code imports necessary libraries, constructs a message to be signed, encodes and signs the message, and sends an API request to edit the file on ShdwDrive.
import bs58 from 'bs58'
import nacl from 'tweetnacl'
// `storageAccount` is the string representation of a storage account pubkey
// `fileName` is the name of the file to be edited
// `sha256Hash` is the sha256 hash of the new file's contents
const message = `ShdwDrive Signed Message:\n StorageAccount: ${storageAccount}\nFile to edit: ${fileName}\nNew file hash: ${sha256Hash}`
// Expect the final message string to look something like this if you were to output it
// ShdwDrive Signed Message:
// Storage Acount: ABC123
// File to delete: https://shadow-drive.genesysgo.net/ABC123/file.png
// If the message is not formatted like above exactly, it will fail message signature verification
// on the ShdwDrive Network side.
const encodedMessage = new TextEncoder().encode(message);
// Uses https://github.com/dchest/tweetnacl-js to sign the message. If it's not signed in the same manor,
// the message will fail signature verification on the Shdw Network side.
// This will return a base58 byte array of the signature.
const signedMessage = nacl.sign.detached(encodedMessage, keypair.secretKey);
// Convert the byte array to a bs58-encoded string
const signature = bs58.encode(signedMessage)
const fd = new FormData();
fd.append("file", fileData, {
contentType: fileContentType as string,
filename: fileName,
});
fd.append("signer", keypair.publicKey.toString())
fd.append("message", signature)
fd.append("storage_account", storageAccount)
const uploadResponse = await fetch(`${SHDW_DRIVE_ENDPOINT}/edit`, {
method: "POST",
body: fd,
});
Example - Deleting a File from ShdwDrive using Signed Message and API
In this example, we demonstrate how to delete a file from the ShdwDrive using a signed message and the ShdwDrive API. The code first constructs a message containing the storage account and the file URL to be deleted. It then encodes and signs the message using the tweetnacl library. The signed message is then converted to a bs58-encoded string. Finally, a POST request is sent to the ShdwDrive API endpoint to delete the file.
import bs58 from 'bs58'
import nacl from 'tweetnacl'
// `storageAccount` is the string representation of a storage account pubkey
// `url` is the link to the ShdwDrive file, just like the previous implementation needed the url input
const message = `ShdwDrive Signed Message:\nStorageAccount: ${storageAccount}\nFile to delete: ${url}`
// Expect the final message string to look something like this if you were to output it
// ShdwDrive Signed Message:
// Storage Acount: ABC123
// File to delete: https://shadow-drive.genesysgo.net/ABC123/file.png
// If the message is not formatted like above exactly, it will fail message signature verification
// on the ShdwDrive Network side.
const encodedMessage = new TextEncoder().encode(message);
// Uses https://github.com/dchest/tweetnacl-js to sign the message. If it's not signed in the same manor,
// the message will fail signature verification on the Shdw Network side.
// This will return a base58 byte array of the signature.
const signedMessage = nacl.sign.detached(encodedMessage, keypair.secretKey);
// Convert the byte array to a bs58-encoded string
const signature = bs58.encode(signedMessage)
const deleteRequestBody = {
signer: keypair.publicKey.toString(),
message: signature,
location: options.url
}
const deleteRequest = await fetch(`${SHDW_DRIVE_ENDPOINT}/delete-file`, {
method: "POST",
headers: {
"Content-Type": "application/json"
},
body: JSON.stringify(deleteRequestBody)
})
