class beem.storage.DataDir

Bases: object

This class ensures that the user’s data is stored in its OS preotected user directory:

OSX:

• ~/Library/Application Support/<AppName>

Windows:

• C:Documents and Settings<User>Application DataLocal Settings<AppAuthor><AppName>
• C:Documents and Settings<User>Application Data<AppAuthor><AppName>

Linux:

• ~/.local/share/<AppName>

Furthermore, it offers an interface to generated backups in the backups/ directory every now and then.

appauthor = 'beem'

appname = 'beem'

clean_data()

Delete files older than 70 days

data_dir = '/home/docs/.local/share/beem'

mkdir_p()

Ensure that the directory in which the data is stored exists

recover_with_latest_backup(backupdir='backups')

Replace database with latest backup

refreshBackup()

Make a new backup

sqlDataBaseFile = '/home/docs/.local/share/beem/beem.sqlite'

sqlite3_backup(backupdir)

Create timestamped database copy

sqlite3_copy(src, dst)

Copy sql file from src to dst

storageDatabase = 'beem.sqlite'

class beem.storage.Key

Bases: beem.storage.DataDir

This is the key storage that stores the public key and the (possibly encrypted) private key in the keys table in the SQLite3 database.

add(wif, pub)

Add a new public/private key pair (correspondence has to be

checked elsewhere!)

Parameters:

• pub (str) – Public key
• wif (str) – Private key

create_table()

Create the new table in the SQLite database

delete(pub)

Delete the key identified as pub

Parameters:pub (str) – Public key

exists_table()

Check if the database table exists

getPrivateKeyForPublicKey(pub)

Returns the (possibly encrypted) private key that

corresponds to a public key

Parameters:pub (str) – Public key

The encryption scheme is BIP38

getPublicKeys()

Returns the public keys stored in the database

updateWif(pub, wif)

Change the wif to a pubkey

Parameters:

• pub (str) – Public key
• wif (str) – Private key

wipe(sure=False)

Purge the entire wallet. No keys will survive this!

class beem.storage.MasterPassword(password)

Bases: object

The keys are encrypted with a Masterpassword that is stored in the configurationStore. It has a checksum to verify correctness of the password

changePassword(newpassword)

Change the password

config_key = 'encrypted_master_password'

This key identifies the encrypted master password stored in the confiration

newMaster()

Generate a new random masterpassword

password = ''

saveEncrytpedMaster()

Store the encrypted master password in the configuration store

static wipe(sure=False)

Remove all keys from configStorage

class beem.storage.Token

Bases: beem.storage.DataDir

This is the token storage that stores the public username and the (possibly encrypted) token in the token table in the SQLite3 database.

add(name, token)

checked elsewhere!)

Parameters:

• name (str) – Public name
• token (str) – Private token

Create the new table in the SQLite database

delete(name)

Delete the key identified as name

Parameters:name (str) – Public name

exists_table()

Check if the database table exists

getPublicNames()

Returns the public names stored in the database

getTokenForPublicName(name)

Returns the (possibly encrypted) private token that

corresponds to a public name

Parameters:pub (str) – Public name

The encryption scheme is BIP38

updateToken(name, token)

Change the token to a name

Parameters:

• name (str) – Public name
• token (str) – Private token

wipe(sure=False)
