• PHP5 password hash generator. PHP passwordhash is a predefined (built in) function using salt key. Implemented in php 5.1. Easily verifiable with passwordverify function what used for verify that a password matches a hash. Perhaps non-reversable. Easiest way to reset password or change password.
• Therefore, the salt should be random string with at least as many variable bits, as there are bits in the hash result. In the user database, store username, the randomly generated salt for that user, and the result of hashing the salt-password-string.

php 5.4.0 or newer.

Generate a SHA-256 hash with this free online encryption tool. To create a SHA-256 checksum of your file, use the upload feature. To further enhance the security of you encrypted hash you can use a shared key. You can modify it to add particular suffixes and prefixes to the generated random string. People who are using PHP 7 can improve the string generation further by using the cryptographically secure function randomint instead of mtrand. Generate Random Hexadecimal Strings. If you want to generate random hexadecimal strings in PHP, you can.

php5-gmp needs to be installed.

If you want to launch the test file you need to be under a unix system with libbitcoin intalled on it.

Installation

Best way is to use composer

Alternatively add following snippet in you composer.json

Instanciation

Set a private key

examples of private keys :

4C28FCA386C7A227600B2FE50B7CAE11EC86D3BF1FBE471BE89827E19D72AA1D00FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEFFFFFC

Generate a random private key

The nonce is optional, typically the nonce is a chunck of random data you get from the user. This can be mouse coordinates.Using a nonce adds randomness, which means the generated private key is stronger.

Get the private key

Returns the private key.

Get the Wif

returns the private key under the Wallet Import Format

Get the Public Key

Returns the compressed public key.The compressed PubKey starts with 0x02 if it's y coordinate is even and 0x03 if it's odd, the next 32 bytes corresponds to the x coordinates.

Example : 0226c50013603b085fbc26411d5d7e564b252d88964eedc4e01251d2d495e92c29 Node generate public provate keys.

Get the Uncompressed Public Key

Returns the uncompressed PubKey.The uncompressed PubKey starts with 0x04, the next 32 bytes are the x coordinates, the last 32 bytes are the y coordinates.

Example : 04c80e8af3f1b7816a18aa24f242fc0740e9c4027d67c76dacf4ce32d2e5aace241c426fd288a9976ca750f1b192d3acd89dfbeca07ef27f3e5eb5d482354c4249

Get the coordinates of the Public Key

Returns an array containing the x and y coordinates of the public key Activate microsoft office 2013 key generator.

Example :Array ( [x] => a69243f3c4c047aba38d7ac3660317629c957ab1f89ea42343aee186538a34f8 [y] => b6d862f39819060378542a3bb43ff76b5d7bb23fc012f09c3cd2724bebe0b0bd )

Get the Address

Returns the compressed Bitcoin Address.

Get the uncompressed Address

Returns the uncompressed Bitcoin Address.

Validate an address

Returns true if the address is valid and false if it isn't

Validate a Wif key

Returns true if the WIF key is valid and false if it isn't

Sign a message

Returns a satoshi client standard signed message.

Php Hash Function

verify a message

Returns true if the signature is matching the address and false if it isn't.

sign a sha256 hash

Returns a DER encoded hexadecimal signature.

Php Generate Random Alphanumeric String

verify a signature

Returns true if the signature is matching the public key and false if it isn't.

What is Bitcoin?

Php Generate Random Hash Keys

Bitcoin is a cryptocurrency, a form of electronic cash. It is a decentralized digital currency without a central bank or single administrator that can be sent digitally from user-to-user on the peer-to-peer Bitcoin network without the need for intermediaries.
A Bitcoin Address is an ID of 26-35 alphanumeric numbers, that represents a possible destination for an (incoming) Bitcoin payment for example to a Bitcoin Wallet. A Bitcoin wallet address, which is a hash of the corresponding public key, always starts either with number 1 or with the number 3.
