infinity.sha256¶

Provides SHA-256 encryption and decryption functionality for strings, files and streams.

Module: infinity.crypto

Example:

infinity.loadModule('infinity.crypto');

let hash = infinity.sha256.hash("dataToHash");
console.debug(hash);
//0e396429f7fb2760a15e7d2326ec64b3d7db2c52b673a77c15a8250d66a94c93

hash()¶

Returns the SHA256 hash of the given string.

Signature:

hash( value: string ): string

Parameters:

• value: string

  The string to be hashed.

Return type: string

Example:

infinity.loadModule('infinity.crypto');
let hash = infinity.sha256.hash(dataToHash);

hashFile()¶

Returns the SHA256 hash of the contents of the given file.

Signature:

hashFile( fileName: string ): string

Parameters:

• fileName: string

  Filename, relative path (location relative to the folder with the used INFINITY.JS executable file) or absolute path to the file which has to be hashed.

Return type: string

Example:

infinity.loadModule('infinity.crypto');
let hash = infinity.sha256.hashFile('dataToHash.txt');

hashStream()¶

Returns the SHA256 hash of the given stream.

Signature:

hashStream( stream: infinity.stream ): string

Parameters:

• stream: infinity.stream

  The stream object for building the hash. See infinity.stream.

Return type: string

Example:

infinity.loadModule('infinity.crypto');
let hash = infinity.sha256.hashStream(stream);

hmac()¶

Returns a keyed hash value using the HMAC method.

Signature:

hash( value: string, key: string ): string

Parameters:

• value: string

  Message to be hashed.

• key: string

  Shared secret key used for generating the HMAC variant of the message digest.

Return type: string

Example:

infinity.loadModule('infinity.crypto');
let hmac = infinity.sha256.hmac(value, key);
