Bitcoin passphrase generator
Each bit chunk of data will map to a word from the BIP39 word list You have seen the word "bit" used a few times in this article. A bit represents 0's and 1's. It is the smallest representation of data we have, and it is expressed in a language our computers understand. Your original source of random data or entropy plus the SHA checksum is divisible by The BIP39 word list contains words, and each word on the list maps to 11 bits of data.
It is important that you slice the bit chunks in sequential order. This means going from left to right, every 11 bits is grouped together. Every 11 bits represents a word in your seed phrase, and the order of the words has to be correct. The next step is to convert your bit sequence into decimal format. This will give you a number that maps to the BIP39 word list.
Now, in the correct order, map each bit sequence to the matching word in the BIP39 word list. Finally, this is your seed phrase! It's important to highlight that some word lists for BIP39 might start with 1. In code, the first number is always 0. This means that words are listed as , not If your BIP39 word list starts with 1 instead of 0, you will need to subtract 1 from the word list numbers to get the correct word. The importance of Random Number Generation or RNG Going back to generating your initial source of randomness: Once you generate the needed entropy, the remaining process of getting the seed phrase is simply math and cryptography.
In practice, this means that when generating a seed phrase, the initial source of entropy is both the most important step, and also the step in which you have the most control over the result. There are many ways to generate entropy: flipping a coin, rolling dice, dealing a deck of cards, recording ambient sound, and many more. The goal here is to get as close to true randomness as possible. If you are using a process that is not sufficiently random, an attacker can recreate your seed phrase.
In the following sections of this article, we will cover different approaches for how to generate entropy, and thus generate your seed phrase. What are the security considerations of generating your own seed phrase? Taking control over the generation of your seed phrase provides the ability to increase the entropy of your seed phrase, thus increasing the security of your entire wallet.
This does not come without risks - a single mistake can result in a less secure wallet, even lost funds. When generating your own seed phrase, security must be top of mind throughout the whole process. The most crucial part of generating your seed phrase rests with the generation of entropy, which is the first step of generating your seed phrase. Your seed phrase can have 12, 15, 18, 21, or 24 words. The more words in your seed phrase, the higher the entropy, which means higher security.
A correctly generated word seed phrase will ALWAYS produce a wallet that is more secure than a 12 word seed phrase. Many wallets today only produce word seed phrases in their built-in wallet creation workflow, but it's important to note that word seed phrases are still very secure.
The only parameter that can be changed is the source of entropy. This is very important because if the source of entropy is corrupted, an attacker can potentially regenerate your wallet and steal your funds. Generating entropy can be done manually or with a computer. Both methods have pros and cons.
Secret Ninja This generator comes from a static character-to-string assignment that produces pronounceable Asian-styled words. As such, there are only 26 assignments, providing about 4. There are three strings concatenated together per hyphenated word. I've seen other skits by comedians where they use made-up words to characterize Bill Cosby, so I figured I would create a list of these words, and see how they fell out.
There are 32 unique words, providing exactly 5-bits of entropy per word. Unlike the Bubble Babble and Secret Ninja generators, this generator uses both uppercase and lowercase Latin characters. Korean K-pop In following with the Bill Cosby Bebop generator, I created a Korean "K-pop" generator that used the most common male and female Korean names, providing exactly 6-bits of entropy per name.
I got the list of names from various sites listing common male and female Korean names. Random These are random strings provided as a last resort for sites or accounting software that have very restrictive password requirements. These passwords will be some of the shortest generated while meeting the same minimum entropy requirement. Because these passwords are not memorable, they should be absolutely stored in a password manager you should be using one anyway.
Base Uses all graphical U. ASCII characters does not include horizontal space. Each character provides about 6. This password will contain ambiguous characters. Each character provides exactly 6-bits of entropy. Base Uses the characters defined in RFC , which strives to use an unambiguous character set. Each character provides exactly 5-bits of entropy.
Base Uses all digits and lowercase characters "a" through "f". Each character provides exactly 4-bits of entropy. This password will contain fully unambiguous characters. Base Uses strictly the digits "0" through "9". This is mostly useful for PINs or other applications where only digits are required. Each digits provides about 3. Emoji: There are emoji glyphs provided by that font, yielding about 9. One side-effect, is that even though there is a character count in the generator box, each glyph may be more than 1 byte, so some input forms may count that glyph as more than 1 character.
Regardless, the minimum entropy is met, so the emoji password is still secure. I want to say something a bit extra about the Emoji generator. With the rise of Unicode and the UTF-8 standard, and the near ubiquitous popularity of smartphones and mobile devices, having access to non-Latin character sets is becoming easier and easier.
So, if Unicode is vastly becoming the norm, why not take advantage of it while having a little fun? I opted for the black-and-white font, as opposed to the color font, to stay consistent with the look and feel of the other generators. This generator uses the emoji character sets provided by Google's Noto Emoji fonts, as that makes it easy for me to support the font in CSS 3, allowing every browser that supports CSS 3 to take advantage of the font and render the glyphs in a standard fashion.
The license is also open so that I can redistribute the font without paying royalties, and others can do the same. Screenshots The post wouldn't be complete without some screenshots. The generator is both desktop friendly, fitting comfortably in a x screen resolution, as well a mobile friendly, working well on even some of the oldest mobile devices.

The First step is to select the word 12 or 24 then click on generate button. It will generate a random bip39 seed phrase. If you want to check the balance of a particular seed, you can click on the check balance button, which is shown below. Currently, we do not check the balance of Bitcoin, but we will do it later. We only check the balance of Ethereum, Binance smart chain, and Matic Blockchain.
You can check the balance of all 3 Blockchain by entering your Ethereum Public address. Generating less than 12 words is easy to guess and less secure. You may input a present BIP39 mnemonic, or generate a brand new random one. Typing your own twelve words will possibly no longer work as you assume because the words require a particular structure the final phrase contains a checksum.
For more info, see the BIP39 spec. The seed phrase is a series of words produced by your crypto wallet that give you access to the crypto associated with that wallet. Think of a wallet like a crypto password manager, and a seed phrase like a master password. As long as you have your seed sentence, you will be able to access every crypto associated with the wallet that produced the sentence — even if you lose or delete the wallet.
How does the seed phrase work? When you create a crypto wallet, the seed phrase is automatically generated. The seed phrase represents a long series of random numbers — and your wallet uses it to generate secret keys that allow you to send and use your crypto. The reason the phrase given to you is in the form of words rather than a long series of random numbers is that people are better at remembering and interacting with word order. But you should not rely on your memory to preserve the phrases of your seed.
Three words are much easier to remember than a series of random characters letters and numbers yet they are much harder to hack. However it looks like a set of words in the Mycelium to generate these phrases is limited - at least Ive got a passphrase with one word repeated two times. Source: pinterest. What is a passphrase.
