Splunk base64 decode8/17/2023 ![]() ![]() Returns a string run through python unicode_escape (i.e. Returns a string where control characters,, and non-ASCII characters are backslash escaped (e.g. Returns a decoded version of the input based on the codec, python codec list is available on Set the count to 'null' to return from the start offset to the end of the input. Returns a substring of the input, starting at the index offset with the number of characters count. Outputs the current state as UTF-8 to the field name. Non-printable characters will be replaced with a period. Recalls the previously saved state name from memory. Saves the current state to memory as name. Transforms hexadecimal input into its byte form. Transforms input into its hexadecimal representation. Implements the RC4 cipher against the field with the supplied key. The key can be provided as a string or integer. Implements basic XOR cipher against the field with the supplied key. The count argument specifies the amount to rotate and must be an integer. Implements rotate-on-right to each character within the string using an 8 bit boundary. Implements rotate-on-left to each character within the string using an 8 bit boundary. The count argument specifies the amount to shift and must be an integer. Pass the output of hex to emit with the argument 'decrypted', creating a decrypted field.Pass the output of b64 to xor as input with the argument 's\圆5cr\圆5t'.Pass the value of the hostname field to b64 as input. ![]() | decrypt field=hostname b64 xor('s\圆5cr\圆5t') hex emit('decrypted') FUNCTIONSĮach function passed as an argument will be executed in order, with the output of the previous function provided as input to the next. Note: If a field argument is passed and the field does not exist in the current record being processed, no error or warning will be given. If no field argument is passed then _raw will be used by default. The field argument specifies the Splunk field to use as input. The input field is not modified in place. Note: Fields must be output via the emit function. If the emit function is not mentioned, an emit('decrypted') is automatically added so the data is output | decrypt field=sourcetype hex() emit('sourcetype') The following example will transform the sourcetype field into its hex representation: It takes the required field to manipulate and then one or more functions as arguments. UsageĭECRYPT is implemented as a single search command which exposes a number of data manipulation functions. _| _/_ _ _._._/ |_ĭECRYPT is a set of Splunk commands which provide encryption andĭecryption routines commonly used in malware communication and dataĭECRYPT is a standard Splunk App and requires no special configuration.
