Are md5 and sha1 considered encryption methods in PHP or are they used for something else?

MD5 and SHA1 are not encryption methods in PHP; instead, they are hashing algorithms used for generating unique fixed-size hash values from input data. Hashing is a one-way process that converts input data into a fixed-length string of characters, making it useful for verifying data integrity and storing passwords securely. 

// Example of using MD5 hashing in PHP
$input_data = "Hello World";
$hashed_data = md5($input_data);
echo "MD5 Hash: " . $hashed_data;

// Example of using SHA1 hashing in PHP
$input_data = "Hello World";
$hashed_data = sha1($input_data);
echo "SHA1 Hash: " . $hashed_data;
