How We Use SHA-256

SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function used to ensure data integrity. At Quanta Payment, we use SHA-256 to securely hash sensitive information before storing or verifying it.

What is SHA-256?

SHA-256 is part of the SHA-2 family, developed by the NSA. It takes an input and produces a fixed 256-bit (32-byte) hash. It is irreversible and widely used in blockchain technologies.

Example:

Input: "quantapayment"

Output (SHA-256 Hash):
2f3dba7bc6b5fc0c7f4b1f42c45e9a0e51c6ad56fa1e37b4be2f55e8e2a0a73e

Usage in Quanta Payment

  • Password hashing before storing in our database
  • Transaction data integrity verification
  • Ensuring immutability in blockchain operations

SHA-256 is not encryption but a one-way hashing method. This means the original input cannot be retrieved from the hash.
