The crypto.getHashes() method is an inbuilt application programming interface of crypto module which is used to display the names of all the supported hash algorithms in an array.
Syntax:
crypto.getHashes()
Parameters: This method doesn’t accept any parameters.
Return Value: It returns the name of all the supported hash algorithms.
Below example illustrate the use of crypto.getHashes() method in Node.js:
Example:
// Node.js program to demonstrate the // crypto.getHashes() method // Including crypto module const crypto = require('crypto');
// Calling getHashes method const hash = crypto.getHashes(); // Prints all the supported hash algorithms console.log("The list of all the hash "
+ "algorithms are : ", hash);
|
Output:
The list of all the hash algorithms are : [ 'RSA-MD4', 'RSA-MD5', 'RSA-MDC2', 'RSA-RIPEMD160', 'RSA-SHA1', 'RSA-SHA1-2', 'RSA-SHA224', 'RSA-SHA256', 'RSA-SHA3-224', 'RSA-SHA3-256', 'RSA-SHA3-384', 'RSA-SHA3-512', 'RSA-SHA384', 'RSA-SHA512', 'RSA-SHA512/224', 'RSA-SHA512/256', 'RSA-SM3', 'blake2b512', 'blake2s256', 'id-rsassa-pkcs1-v1_5-with-sha3-224', 'id-rsassa-pkcs1-v1_5-with-sha3-256', 'id-rsassa-pkcs1-v1_5-with-sha3-384', 'id-rsassa-pkcs1-v1_5-with-sha3-512', 'md4', 'md4WithRSAEncryption', 'md5', 'md5-sha1', 'md5WithRSAEncryption', 'mdc2', 'mdc2WithRSA', 'ripemd', 'ripemd160', 'ripemd160WithRSA', 'rmd160', 'sha1', 'sha1WithRSAEncryption', 'sha224', 'sha224WithRSAEncryption', 'sha256', 'sha256WithRSAEncryption', 'sha3-224', 'sha3-256', 'sha3-384', 'sha3-512', 'sha384', 'sha384WithRSAEncryption', 'sha512', 'sha512-224', 'sha512-224WithRSAEncryption', 'sha512-256', 'sha512-256WithRSAEncryption', 'sha512WithRSAEncryption', 'shake128', 'shake256', 'sm3', 'sm3WithRSAEncryption', 'ssl3-md5', 'ssl3-sha1', 'whirlpool' ]
