Cryptographic functions
The following list contains the functions that you can use to compute the secure hash of string values.
For information about using string and numeric fields in functions, and nesting functions, see Evaluation functions.
md5(X)
Description
This function computes and returns the MD5 hash of a string value X.
Usage
You can use this function with the eval, fieldformat, and where commands, and as part of eval expressions.
Basic example
... | eval n=md5(field)
sha1(X)
Description
This function computes and returns the secure hash of a string value X based on the FIPS compliant SHA-1 hash function.
Usage
You can use this function with the eval, fieldformat, and where commands, and as part of eval expressions.
Basic example
... | eval n=sha1(field)
sha256(X)
Description
This function computes and returns the secure hash of a string value X based on the FIPS compliant SHA-256 hash function.
Usage
You can use this function with the eval, fieldformat, and where commands, and as part of eval expressions.
Basic example
... | eval n=sha256(field)
sha512(X)
Description
This function computes and returns the secure hash of a string value X based on the FIPS compliant SHA-512 hash function.
Usage
You can use this function with the eval, fieldformat, and where commands, and as part of eval expressions.
Basic example
... | eval n=sha512(field)
