Warnings

Testing

Node.js

Optionally run the relevant daemon using the --offline option for the duration of the tests. Tests assume the API settings present in lib/config.js.

λ npm run test

Web browsers

As part of the install process, IPFSecret adds a multihash for browser testing and extracts it to .examples/. The password will be justtesting and you can access it over the local web gateway using the same multihash.

API

Please assume the following lines precede these examples:

const IPFSecret = require('ipfsecret'),
    ipfsecret = new IPFSecret();

ipfsecret.add(path, passphrase)

Wraps ipfs.files.add to require a path to add to IPFS and a passphrase for encryption. Encrypts each file found along the path using webcrypto-crypt and appends the .wcrypt suffix before adding.

Add file

ipfsecret.add('./README.md', 'justtesting')
    .then(results => {
        console.log(results);
    })
    .catch(err => {
        console.error(err);
    });

Example:

[ { path: 'README.md.wcrypt',
  hash: 'QmcrMFv4f4yef5EpdM9mUTGiE4msi2VKLmTPbGenRaiKLd',
  size: 20871 } ]

Add directory

ipfsecret.add('./test', 'justtesting')
    .then(results => {
        console.log(results);
    })
    .catch(err => {
        console.error(err);
    });

Example:

[ { path: 'ipfsecret/test/add-indexed.js.wcrypt',
    hash: 'QmPm5MGHooEiDuiJjDg5dFRvaNgyTNYuM7Lx4gqj5k77cB',
    size: 8013 },
  { path: 'ipfsecret/test/add.js.wcrypt',
    hash: 'Qmcdj2aRshwSkVnEUSAANcHEmbyjb1tnt9Cg5Ubh2bxvav',
    size: 6900 },
  { path: 'ipfsecret/test/get.js.wcrypt',
    hash: 'QmXYeFbCBL8vgYKsvy4K98kYNvqDHMXVeEogR6zQzdedg7',
    size: 5322 }...

0 byte files are skipped during encryption. Symbolic links encountered are resolved and encrypted as separate files.

Other options

If the caller passes in an Object instead of passphrase, ipfsecret.add recognizes the following key:value pairs:

  const options = {
      directory: 'mydirname',                 // Use this wrapping dir, default 'ipfsecret'
      hidden: false,                          // Include hidden files.  Default true
      passphrase: 'justtesting',              // Use value to encrypt, always required
      root: true,                             // Return just multihash.  Default false
      suffix: 'myfilesuffix',                 // Use this suffix, default 'wcrypt'
      wcrypt: {config:{crypto:tagLength:112}} // Pass options to webcrypto-crypt (see below)
  };

Root multihash only

The multihash is returned as a Buffer:

const bs58 = require('bs58');

ipfsecret.add('./test', {passphrase:'justtesting', root:true})
    .then(hash => {
        console.log(bs58.encode(hash));
    })
    .catch(err => {
        console.error(err);
    });

Example:

Qmf22oxRTsz6CPWf2xDZeF729xdBx7ULDQsdtqpXYh8UKV

Custom file suffix

ipfsecret.add('./test', {passphrase:'justtesting', suffix: 'shazam'})
    .then(results => {
        console.log(results);
    })
    .catch(err => {
        console.error(err);
    });

Example:

[ { path: 'ipfsecret/test/add-indexed.js.shazam',
    hash: 'QmY4EWxfvBVAUVzpbB7wXhktWLFwE4xunx1jiFbpiNWiKM',
    size: 8013 },
  { path: 'ipfsecret/test/add.js.shazam',
    hash: 'QmRGKq3VHsuX4kyerYE1atNBC7wCu2gRpmxXqocKdXTQsT',
    size: 6900 },
  { path: 'ipfsecret/test/get.js.shazam',
    hash: 'QmRU2qKJBScmedhcDgGGPCvtpWVnasQEJdkF9UvVEM9L7N',
    size: 5322 },...

Custom wrapping dir

ipfsecret.add('./test', {passphrase:'justtesting', directory:'shazam'})
    .then(results => {
        console.log(results);
    })
    .catch(err => {
        console.error(err);
    });

Example:

[ { path: 'shazam/test/add-indexed.js.wcrypt',
    hash: 'QmTWSp9uyPG2DuxFuw3XBhuqJd7cq4zemz4iJqxMw6693r',
    size: 8013 },
  { path: 'shazam/test/add.js.wcrypt',

Custom cryptography settings

To pass custom settings to webcrypto-crypt, use the wcrypt options attribute:

ipfsecret.add('./test', {
    passphrase:'justtesting',
    root: true,
    wcrypt: {
        config: {
            crypto: {
                tagLength: 112
            },
            derive: {
                hash: 'SHA-256',
                length: 192,
                iterations: 5000
            },
            paranoid: true
        }
    }
})
    .then(hash => {
        console.log(hash);
    })
    .catch(err => {
        console.error(err);
    });

ipfsecret.get(hash, passphrase)

Wraps ipfs.files.get to require a multihash for retrieval and a passphrase for decryption. If passphrase is accepted, returns a promise that resolves to an object stream of decrypted file objects.

Any files encountered during an ipfsecret.get operation that could not be decrypted will not be retrieved.

Consider the following IPFS directory, encrypted with the passphrase, "学年別漢字配当表":

Other options

If the caller passes in an Object instead of a passphrase, ipfsecret.get recognizes the following key:value pairs:

const options = {
    passphrase: 'justtesting',               // Use value to encrypt data, always required
    wcrypt: {config:{crypto:tagLength:112}} // Pass options to cryptography package
};

ipfsecret.addIndexed(path, passphrase)

Otherwise identical to ipfsecret.add, ipfsecret.addIndexed adds HTML, JavaScript, CSS, and fonts that together provide a browser interface for listing and decrypting ipfsecret-encrypted files. This is an alias for ipfsecret.add(path, {passphrase: p, indexed: true}.

Add directory and include browser interface files

ipfsecret.addIndexed('./test', 'justtesting')
    .then(results => {
        console.log(results);
    })
    .catch(err => {
        console.error(err);

Other options

Content overrides

In addition to all the options supported by ipfsecret.add, you may override ipfsecret.addIndexed's CSS, font directory, and JavaScript build by passing in overriding options:

ipfsecret.addIndexed('./test', {
    baseCss: './myBase.css',
    dialogCss: './myDialog.css',
    fontCss: './myFonts.css',
    mainCss: './myStyles.css',
    mapCss: './myStyles.css.map',
    fontsDir: './myFontsDirectory',
    jsPath: './myJavaScriptBuild.js',
    passphrase: 'justtesting',
})
    .then(results => {
        console.log(results);
    })
    .catch(err => {
        console.error(err);
    });

ipfsecret.getGatewayList()

Return an array of currently known HTTP/S gateways; used by the command-line utility.

console.log(ipfsecret.getGatewayList());
[ 'https://gateway.ipfs.io',
  'https://earth.i.ipfs.io',
  'https://mercury.i.ipfs.io',
  'https://gateway.ipfsstore.it:8443',
  'https://scrappy.i.ipfs.io',
  'https://chappy.i.ipfs.io' ]

IPFSecret.DEBUG = true | false

If set to true, send debugging statements to stderr. Default false.

IPFSecret.version

Returns the current version of this library, e.g., 0.1.2.

Custom API endpoint

When instantiating a new IPFSecret object, you may optionally pass in options to override the default IPFS connection parameters:

    const ipfsecret = new IPFSecret({
        host: '192.168.1.233',  // default 'localhost'
        port: 5002,             // default 5001
        proto: 'http'           // default 'http'
    });

Implementation

Cryptography

IPFSecret's encryption depends on WebCrypto's SubtleCrypto interface, specifically the algorithms PBKDF2 and AES-GCM. It then marshals the encrypted chunks into IPFS objects and adds these to IPFS as new files. Decryption is carried out via the same SubtleCrypto interface, with the caller supplying the correct passphrase along with the relevant multihash to decrypt the files as they are retrieved. See webcrypto-crypt for more information.

Decrypting IPFS files in the web browser is currently supported but encrypting in the browser is not supported.

Web browsers

HTML page

<p align="center"> <a href="http://pix.toile-libre.org/upload/original/1510603116.png"><img width="50%" height="50%" src="http://pix.toile-libre.org/upload/original/1510603116.png"></a> </p>

By default, IPFSecret publishes the index using the filename ipfsecret.html. This can be overridden to specify any filename but be aware index.html has special meaning for IPFS gateways.

Markup and styling

When calling addIndexed() from JavaScript or specifying the --web argument to the ipfsecret command-line utility, IPFSecret will generate unencrypted HTML pages that contain a directory listing and buttons to decrypt any file by providing the passphrase. The HTML is currently styled using Milligram but as noted in the Content overrides section, you may also specify your own CSS and accompanying fonts.

Decryption

IPFSecret currently accesses encrypted IPFS files from the web browser as Blobs and decrypts them via webcrypto-crypt.

Decrypted file size limits

Filesaver.js documentation shows the download size limits of the various browsers. If IPFSecret detects that an encrypted file is larger than the current browser's limit, instead of decrypting it will display a message suggesting other options. Encrypted files can always be downloaded from the gateway and later decrypted using Node.js or the command-line.

Encrypted file modified times

The Date modified field populated in the web interface reflects the modified time of the original, unencrypted file, versus the time that the encrypted version was created.

Long download times & decryption times

IPFSecret currently relies on the browser's Fetch API to access files as blobs, and there is currently no support in the API for showing download progress. In the case of accessing large files over slow IPFS web gateways, you may end up waiting a good while for the encrypted file to download before decryption can begin, without knowing how much longer the download will take to complete. Decryption in the browser can also be slow, particularly with blobs approaching 500MB or more. There is currently a Todo item to migrate these operations to the Streams API which may improve performance in future releases.

Offline mode

IPFSecret web pages try to detect whether or not the current browser is connected to the internet and, if not connected, attempt to redirect to the local IPFS HTTP gateway. Decryption should work in the browser whether or not the user is connected to the internet, provided the multihashes in question are locally accessible.

Troubleshooting

IPFSecret is not fast. For large directories and files, you may just need to wait it out...

File signature warnings

When decrypting directories that contain the web user interface, the unencrypted web interface files may trigger this warning:

Error: Error: Invalid file signature webcrypto-crypt0.1.15

Invalid index entries

Directories that contained no files or contained only 0-byte files will currently result in invalid links in the HTML indices.

Out of memory

If you hand ipfsecret add a very large directory, you may encounter a fatal error like:

FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

In these cases you might consider writing several directories as separate operations.
