Synopse Open Source

In order to follow best practice, our .private key files are always protected by a password.  A random value with enough length and entropy is always proposed by the ECC tool when a key pair is generated, and could be used directly.
It is always preferred to trust a computer to create true randomness (and SynCrypto.pas's secure TAESPRNG was designed to be the best possible seed, using hardware entropy if available), than using our human brain, which could be defeated by dictionary-based password attacks.
Brute force cracking would be almost impossible, since PBKDF2_HMAC_SHA256 Password-Based Key Derivation Function with 60,000 rounds is used, so rainbow tables (i.e. pre-computed passwords list) will be inoperative, and each password trial would take more time than with a regular Key Derivation Function.

The issue with strong passwords is that they are difficult to remember. If you use not pure random passwords, but some easier to remember values with good entropy, you may try some tools like https://xkpasswd.net/s which returns values like $$19*wrong*DRIVE*read*61$$.
But even then, you will be able to remember only a dozen of such passwords. In a typical public key infrastructure, you may create hundredths of keys, so remembering all passwords is no option for an average human being as (you and) me.

At the end, you end up with using a tool to store all your passwords (last trend is to use an online service with browser integration), or - admit it - store them in an Excel document protected by a password. Most IT people - and even security specialists - end with using such a mean of storage, just because they need it.
The weaknesses of such solutions can be listed:

• How could we trust closed source software and third-party online services?
• Even open source like http://keepass.info/help/base/security.html may appear weak (no PBKDF, no AFSplit, managed C#, SHA as PRNG);
• The storage is as safe as the "master password" is safe;
• If the "master password" is compromised, all your passwords are published;
• You need to know the master password to add a new item to the store.

The ECC tool is able to work in "cheat mode", storing all .private key files generated passwords in an associated .cheat local file, encrypted using a cheat.public key.

As a result:

• Each key pair will have its own associated .cheat file, so you only unleash one key at a time;
• The .cheat file content is meaningless without the cheat.private key and its master password, so you can manage and store them together with your .private files;
• Only the cheat.public key is needed when creating a key pair, so you won't leak your master password, and even could generate keys in an automated way, on a distant server;
• The cheat.private key will be safely stored in a separated place, only needed when you need to recover a password;
• It uses strong File Encryption, with proven PBKDF, AFSplit, AES-PRNG, and ECDH/ECIES algorithms.

There are still a few days for "very early birds" offer for EKON 20 conference, and meet us for 3 sessions (including a half-day training/introduction to mORMot)! Join us the 7-9th of November in Düsseldorf! Our sessions are not restricted to mORMot, but will use mORMot to illustrate some  […]

Some patches, provided by ALFred, did introduce some new platforms under Linux: Linux x86 (aka Intel 32-bit) Linux x64 (aka Intel 64-bit) Linux AARCH32 (aka ARM 32-bit) Linux AARCH64 (aka ARM 64-bit) It needs the latest trunk version of the FPC compiler, and the "Interface Enhanced RTTI"  […]

You should have noticed that Delphi 10.1 Berlin has been released. Our Open Source projects, including mORMot and SynPDF and their associated documentation have been updated to support this new revision. Any additional feedback is welcome, as usual!
