SHA256

This function converts the specified string into a SHA256 hex value hash.

Arguments

SHA256(1,2)

Ordinal Type Required Description
1 String True String to convert
2 String False Character set to use for character-encoding. Valid values are UTF-8 (default) and UTF-16

NOTE: The results of the SHA256 hash are considered one-way, meaning they cannot be decrypted.

Example

%%[

var @emailAddress
var @SHA256EmailAddressUTF8
var @SHA256EmailAddressUTF16

set @emailAddress = AttributeValue("emailAddr") /* value from attribute or DE column in send context */
set @emailAddress = "[email protected]" /* or a literal value */
set @SHA256EmailAddressUTF8  = SHA256(@emailAddress)
set @SHA256EmailAddressUTF16  = SHA256(@emailAddress, "UTF-16")

]%%
emailAddress: %%=v(@emailAddress)=%%
<br>SHA256EmailAddressUTF8: %%=v(@SHA256EmailAddressUTF8)=%%
<br>SHA256EmailAddressUTF16: %%=v(@SHA256EmailAddressUTF16)=%%

Output

emailAddress: [email protected]
