sha256¶

Logically joins all arguments into a single string, and returns its SHA256 digest encoded as a binary string.

 $sha256_raw = sha256('data string');
 #or
 $sha256_raw = sha256('any data', 'more data', 'even more data');

sha256_hex¶

Logically joins all arguments into a single string, and returns its SHA256 digest encoded as a hexadecimal string.

 $sha256_hex = sha256_hex('data string');
 #or
 $sha256_hex = sha256_hex('any data', 'more data', 'even more data');

sha256_b64¶

Logically joins all arguments into a single string, and returns its SHA256 digest encoded as a Base64 string, with trailing '=' padding.

 $sha256_b64 = sha256_b64('data string');
 #or
 $sha256_b64 = sha256_b64('any data', 'more data', 'even more data');

sha256_b64u¶

Logically joins all arguments into a single string, and returns its SHA256 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).

 $sha256_b64url = sha256_b64u('data string');
 #or
 $sha256_b64url = sha256_b64u('any data', 'more data', 'even more data');

sha256_file¶

Reads file (defined by filename or filehandle) content, and returns its SHA256 digest encoded as a binary string.

 $sha256_raw = sha256_file('filename.dat');
 #or
 $sha256_raw = sha256_file(*FILEHANDLE);

sha256_file_hex¶

Reads file (defined by filename or filehandle) content, and returns its SHA256 digest encoded as a hexadecimal string.

 $sha256_hex = sha256_file_hex('filename.dat');
 #or
 $sha256_hex = sha256_file_hex(*FILEHANDLE);

BEWARE: You have to make sure that the filehandle is in binary mode before you pass it as argument to the addfile() method.

sha256_file_b64¶

Reads file (defined by filename or filehandle) content, and returns its SHA256 digest encoded as a Base64 string, with trailing '=' padding.

 $sha256_b64 = sha256_file_b64('filename.dat');
 #or
 $sha256_b64 = sha256_file_b64(*FILEHANDLE);

sha256_file_b64u¶

Reads file (defined by filename or filehandle) content, and returns its SHA256 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).

 $sha256_b64url = sha256_file_b64u('filename.dat');
 #or
 $sha256_b64url = sha256_file_b64u(*FILEHANDLE);
