hashWith

hashWith(content: Binary, algorithm: String = "SHA-1"): Binary

Computes the hash value of binary content using a specified algorithm.

The first argument specifies the binary content to use to calculate the hash value, and the second argument specifies the hashing algorithm to use. The second argument must be any of the accepted Algorithm names:

Algorithm names Description

Algorithm names	Description
`MD2`	The MD2 message digest algorithm as defined in RFC 1319.
`MD5`	The MD5 message digest algorithm as defined in RFC 1321.
`SHA-1`, `SHA-256`, `SHA-384`, `SHA-512`	Hash algorithms defined in the FIPS PUB 180-2. SHA-256 is a 256-bit hash function intended to provide 128 bits of security against collision attacks, while SHA-512 is a 512-bit hash function intended to provide 256 bits of security. A 384-bit hash may be obtained by truncating the SHA-512 output.

MD2

The MD2 message digest algorithm as defined in RFC 1319.

MD5

The MD5 message digest algorithm as defined in RFC 1321.

SHA-1, SHA-256, SHA-384, SHA-512

Hash algorithms defined in the FIPS PUB 180-2. SHA-256 is a 256-bit hash function intended to provide 128 bits of security against collision attacks, while SHA-512 is a 512-bit hash function intended to provide 256 bits of security. A 384-bit hash may be obtained by truncating the SHA-512 output.

Parameters

Name Description

Name	Description
`content`	The binary input value to hash.
`algorithm`	The name of the algorithm to use for calculating the hash value of `content`. This value is a string. Defaults to `SHA-1`.

content

The binary input value to hash.

algorithm

The name of the algorithm to use for calculating the hash value of content. This value is a string. Defaults to SHA-1.

Example

This example uses the MD2 algorithm to encrypt a binary value.
