SHA1

This function converts the specified string into a SHA1 hex value hash.

Arguments

SHA1(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 SHA1 hash are considered one-way, meaning they cannot be decrypted.

Example

%%[

var @emailAddress
var @SHA1EmailAddressUTF8
var @SHA1EmailAddressUTF16

set @emailAddress = AttributeValue("emailAddr") /* value from attribute or DE column in send context */
set @emailAddress = "[email protected]" /* or a literal value */
set @SHA1EmailAddressUTF8  = SHA1(@emailAddress)
set @SHA1EmailAddressUTF16  = SHA1(@emailAddress, "UTF-16")

]%%
emailAddress: %%=v(@emailAddress)=%%
<br>SHA1EmailAddressUTF8: %%=v(@SHA1EmailAddressUTF8)=%%
<br>SHA1EmailAddressUTF16: %%=v(@SHA1EmailAddressUTF16)=%%

Output

emailAddress: [email protected]
SHA1EmailAddressUTF8: 349601423ece6853014397f3b5fe44ce8ddd9358
SHA1EmailAddressUTF16: 2eb6923a3078e9cfa0632461098720a99100bcdc
