How to store secure password?

  How to store secure password?   You could use encryption (***). But if there’s a way to encrypt it, then there should be a way to decrypt it.   So, encryption is also vulnerable to hacker’s attack.   One-way hash encryption   So in that condition use "one-way hash encryption" also known as a message digest, digital signature, one-way     encryption, digital fingerprint, or cryptographic hash.   Hashing is different from encryption. Because, encryption is two way, means that you can always decrypt the encrypted text to get the original text. But Hashing is one way; you can never get the original text from the hash value.   Thus it gives more security than encryption.   There are several message-digest algorithms (hashing algorithms) used widely today.   Like – MD5, SHA-1, etc SHA-1 (Secure Hash Algorithm 1) is slower than MD5, but the message digest is larger, which makes it more resistant to brute for...
