Php Generate Api Private Key
Posted : admin On 30.05.2020RS256 is an asymmetric algorithm which means that there are two keys: one public and one private (secret). Auth0 has the secret key, which is used to generate the signature, and the consumer of the JWT has the public key, which is used to validate the signature.
Example for an API Key generator written in PHP. The key that is generated will be 32 non-cryptographic random characters long, and can contain 0-9, a-z (lowercase), A-Z (uppercase). Adding the option for the characters to repeat, creates over 450 quadrillion combinations.
To keep the code short, I generate a random number using rand(48, 122). This number will then be filtered for the ranges of 58 to 64, and 91 to 96. If the random number is present in the previous ranges, the number must be discarded and then recreated. This is done until a number is generated outside of the previous ranges, and this in turn must be completed 32 times. This is done so that the random number can convert into ASCII code (i.e. 0 ; = 0, whitespace added the prevent conversion) to generate the characters mentioned above.
Another option would be to create a random number using rand(0, 61). Then using a switch statement append a string together based upon the result. This method results in code roughly 133 lines in length (excluding comments, but allowing whitespace), while the previous method is 27 lines in length (again excluding comments, but allowing whitespace).
- The only setup needed is to go to the API Keys page and generate an API key. You will be given a private and public key used to authenticate your API calls. You will be given a private and public key used to authenticate your API calls.
- 8.0 Create API for user account 8.1 Create a file for updating user account. This file will return output in JSON format and will accept requests from the specified URL. We'll set the correct headers. Open api folder. Create updateuser.php file. Place the following code.

php 5.4.0 or newer.
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
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
Example :Array ( [x] => a69243f3c4c047aba38d7ac3660317629c957ab1f89ea42343aee186538a34f8 [y] => b6d862f39819060378542a3bb43ff76b5d7bb23fc012f09c3cd2724bebe0b0bd )
Get the Address
Returns the compressed CPUchain Address.
For example, an account called 'autodrop' runs a cron job which SCPs files into a directory and invokes a command on the remote host to process the files. Generate host keys for multiple hosts.
Get the uncompressed Address
Returns the uncompressed CPUchain Address.
