Use Secure Passwords for your Self-Generated Private Keys
One of the lesser known features of Bitcoin is that the private keys, which form the basis for a Bitcoin address, do not need to be generated randomly; instead, one can generate a Bitcoin address, fully compatible with Blockchain.info's wallet and Armory, using nothing but standard easily available cryptographic tools and a password of your choice. If....

C'mon, show me your passwords. We all know our default password like the back of our hands. Websites, email accounts, wallets - a mess of places and ideas - who can afford to think of a unique and secure password for each new login registration? Note to readers: Part Two - Motor Memory Passphrases has been published. Well, the level of vulnerability has just ticked up by two notches with the discovery of the OpenSSL Heartbleed Bug this April.

In this age of hacks and scandals, are passwords really capable of protecting your bitcoins?

Some people protect their bitcoins by storing them in paper wallets, embedding them in a....
Bitcoin security platform BitGo announced the launch of the first automated open source Key Recovery Service (KRS) software that allows generating, securing and storing private backup keys, which should make it one of the most secure Bitcoin vaults in the world. A major problem Bitcoin wallet users encounter is the security of the keys. While most new secure wallets implement multi-signature, in which 1 or 2 keys are created and stored by the user, a problem arises when the user forgets one of the passwords as they would then lose access to the wallet and its contents. However, BitGo’s new....
Clef, an authentication client that combines several solutions for problems posed by centralized systems, continues gaining ground. Initially launched in early 2013, its appeal has recently inspired a partnership with AlphaPoint, a lead provider of cryptocurrency exchange software. Brennen Byrne, Clef's founder, claims that Bitcoin inspired the project. What similarities do these systems really bare, though? Like Bitcoin, Clef employs RSA cryptography - the use of private/public key pairs for signing and validating messages - in order to surmount the vulnerabilities posed by storing....
