## Detailed Description

MD5 checksum class.

Create one of these with a block of source data or a stream, and it calculates the MD5 checksum of that data.

You can then retrieve this checksum as a 16-byte block, or as a hex string.

## Constructor & Destructor Documentation

## MD5() [1/7]

MD5::MD5 | ( |  | ) |

Creates a null MD5 object.

## MD5() [2/7]

MD5::MD5 | ( | const MD5 & |  | ) |

Creates a copy of another MD5.

## MD5() [3/7]

MD5::MD5 | ( | const MemoryBlock & |  | ) |

explicit noexcept

Creates a checksum for a block of binary data.

## MD5() [4/7]

MD5::MD5 | ( | const void * | data,
|  | size_t | numBytes
| ) |  |

noexcept

Creates a checksum for a block of binary data.

## MD5() [5/7]

MD5::MD5 | ( | InputStream & | input,
|  | int64 | numBytesToRead = `-1`
| ) |  |

Creates a checksum for the input from a stream.

This will read up to the given number of bytes from the stream, and produce the checksum of that. If the number of bytes to read is negative, it'll read until the stream is exhausted.

## MD5() [6/7]

MD5::MD5 | ( | const File & |  | ) |

explicit

Creates a checksum for the contents of a file.

## MD5() [7/7]

MD5::MD5 | ( | CharPointer_UTF8 | utf8Text | ) |

explicit noexcept

Creates a checksum of the characters in a UTF-8 buffer.

E.g.

MD5 checksum (myString.toUTF8());

## ~MD5()

MD5::~MD5 | ( |  | ) |

Destructor.

## Member Function Documentation

## operator=()

MD5& MD5::operator= | ( | const MD5 & |  | ) |

Copies another MD5.

## getRawChecksumData()

MemoryBlock MD5::getRawChecksumData | ( |  | ) | const

Returns the checksum as a 16-byte block of data.

## getChecksumDataArray()

const uint8* MD5::getChecksumDataArray | ( |  | ) | const

noexcept

Returns a pointer to the 16-byte array of result data.

## toHexString()

String MD5::toHexString | ( |  | ) | const

Returns the checksum as a 32-digit hex string.

## fromUTF32()

static MD5 MD5::fromUTF32 | ( | StringRef |  | ) |

static

Creates an MD5 from a little-endian UTF-32 encoded string.

Note that this method is provided for backwards-compatibility with the old version of this class, which had a constructor that took a string and performed this operation on it. In new code, you shouldn't use this, and are recommended to use the constructor that takes a CharPointer_UTF8 instead.

## operator==()

bool MD5::operator== | ( | const MD5 & |  | ) | const

noexcept

## operator!=()

bool MD5::operator!= | ( | const MD5 & |  | ) | const

noexcept
