Cryptographic

Cryptographic functions return hashes in bytes, so you need to convert your bytes to a Base64-encoded string to send your data to a destination. See the base64_encode scalar function.

md5(input)

This function computes and returns the MD5 hash of a byte value X. Because this function takes bytes as its input, first use the to_bytes conversion function to convert your string into a byte string.

Function Input
input: bytes
Function Output
bytes

SPL2 examples

...| eval hashed_bytes_md5=md5(to_bytes("hash-me"));

Alternatively, you can use named arguments. See SPL2 syntax for more details.

...| eval hashed_bytes_md5=md5(input: to_bytes("hash-me"));

sha1(input)

This function computes returns the secure hash of a byte value X based on the FIPS compliant SHA-1 hash function. Because this function takes bytes as its input, first use the to_bytes conversion function to convert your string into a byte string.

Function Input
input: bytes
Function Output
bytes

SPL2 examples

hashed_bytes_sha1=sha1(to_bytes("hash-me"));

Alternatively, you can use named arguments. See SPL2 syntax for more details.

hashed_bytes_sha1=sha1(input: to_bytes("hash-me"));

sha256(input)

This function computes and returns the secure hash of a byte value X based on the FIPS compliant SHA-256 hash function. Because this function takes bytes as its input, first use the to_bytes conversion function to convert your string into a byte string.

Function Input
input: bytes
Function Output
bytes

SPL2 examples

...| eval hashed_bytes_sha256=sha256(to_bytes("hash-me"));

Alternatively, you can use named arguments. See SPL2 syntax for more details.

...| eval hashed_bytes_sha256=sha256(input: to_bytes("hash-me"));

sha512(input)

This function computes and returns the secure hash of a byte value X based on the FIPS compliant SHA-512 hash function. Because this function takes bytes as its input, first use the to_bytes conversion function to convert your string into a byte string.

Function Input
input: bytes
Function Output
bytes

SPL2 examples

...| eval hashed_bytes_sha512=sha512(to_bytes("hash-me"));

Alternatively, you can use named arguments. See SPL2 syntax for more details.

...| eval hashed_bytes_sha512=sha512(input: to_bytes("hash-me"));
