# Reverse Hex

Reverse hexadecimal values effortlessly with our Reverse Hex tool. Ideal for cryptography and data analysis, ensuring unique and precise transformations.

A hexadecimal number, often referred to as "hex number," is a number system that uses base-16, meaning it represents numbers using 16 distinct symbols. These symbols are typically the digits 0-9 and the letters A-F (or a-f), where A-F represent the decimal values 10-15, respectively. For example:

- Decimal 0 is represented as 0x0 in hexadecimal.
- Decimal 10 is represented as 0xA in hexadecimal.
- Decimal 15 is represented as 0xF in hexadecimal.
- Decimal 16 is represented as 0x10 in hexadecimal.

The process of reversing the bytes of a hexadecimal number involves reversing the order of the bytes (pairs of digits) within the hexadecimal representation. Here's how it works with an example:

Suppose we have a hexadecimal number `0x1A2B3C4D`

. In this case, the bytes are `1A`

, `2B`

, `3C`

, and `4D`

. To reverse the bytes, we swap their positions:

Original: `0x1A2B3C4D`

Reversed: `0x4D3C2B1A`

This reversal effectively swaps the positions of the bytes while maintaining their internal order within each byte.

Let's demonstrate this process with another example:

Original Hexadecimal Number: `0xAABBCCDD`

Bytes: `AA`

, `BB`

, `CC`

, `DD`

Reversed Bytes: `DD`

, `CC`

, `BB`

, `AA`

Reversed Hexadecimal Number: `0xDDCCBBAA`

Similarly, for `0xA912CBD4`

:Bytes: `A9`

, `12`

, `CB`

, `D4`

Reversed Bytes: `D4`

, `CB`

, `12`

, `A9`

Reversed Hexadecimal Number: `0xD4CB12A9`

This process involves reversing the order of bytes while keeping the bytes themselves intact within each pair.
