All DSP releases prior to DSP 1.4.0 use Gravity, a Kubernetes orchestrator, which has been announced end-of-life. We have replaced Gravity with an alternative component in DSP 1.4.0. Therefore, we will no longer provide support for versions of DSP prior to DSP 1.4.0 after July 1, 2023. We advise all of our customers to upgrade to DSP 1.4.0 in order to continue to receive full product support from Splunk.
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
When working in the SPL View, you can write the function by using the following syntax.
...| eval hashed_bytes_md5=md5(to_bytes("hash-me"));
Alternatively, you can use named arguments.
...| 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
When working in the SPL View, you can write the function by using the following syntax.
...| eval hashed_bytes_sha1=sha1(to_bytes("hash-me"));
Alternatively, you can use named arguments.
...| eval 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
When working in the SPL View, you can write the function by using the following syntax.
...| eval hashed_bytes_sha256=sha256(to_bytes("hash-me"));
Alternatively, you can use named arguments.
...| 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
When working in the SPL View, you can write the function by using the following syntax.
...| eval hashed_bytes_sha512=sha512(to_bytes("hash-me"));
Alternatively, you can use named arguments.
...| eval hashed_bytes_sha512=sha512(input: to_bytes("hash-me"));
