Package io.ktor.util

Stub implementation that always fails. Will be removed so no public signatures should rely on it

Specifies a key for an attribute in Attributes

Map of attributes accessible by AttributeKey in a typed manner

A map with case insensitive String keys

Stateful digest class specified to calculate digest.

Content encoder.

This implementation does only generate nonce values but doesn't validate them. This is recommended for testing only.

Empty Encoder that doesn't do any changes.

API marked with this annotation is internal, and it is not intended to be used outside Ktor. It could be modified or removed without any notice. Using it outside Ktor could cause undefined behaviour and/or any unexpected effects.

API marked with this annotation is experimental and is not guaranteed to be stable.

Represents a nonce manager. Its responsibility is to produce nonce values and verify nonce values from untrusted sources that they are provided by this manager. This is usually required in web environment to mitigate CSRF attacks. Depending on it's underlying implementation it could be stateful or stateless. Note that there is usually some timeout for nonce values to reduce memory usage and to avoid replay attacks. Nonce length is unspecified.

API marked with this annotation is intended to become public in the future version. Usually it means that the API can't be public at the moment of development due to compatibility guarantees restrictions.

Stateless nonce manager implementation with HMAC verification and timeout. Every nonce provided by this manager consist of a random part, timestamp and HMAC.

Create a digest function with the specified algorithm and salt

Encode bytes as a HEX string with no spaces, newlines and 0x prefixes.

Decode bytes from HEX string. It should be no spaces and 0x prefixes.

Check if Char is in lower case

Moves bytes from this buffer to the destination buffer

Moves bytes from this buffer into newly created ByteArray and returns it

Remove all redundant . and .. path elements. Leading .. are also considered redundant.

Print Job children tree.

Adds all attributes from another collection, replacing original values if any.

Read from a NIO channel into the specified buffer Could return 0 if the channel is non-blocking or buffer has no free space

Compute SHA-1 hash for the specified bytes

Compute SHA-1 hash for the specified bytes

Compute SHA-1 hash for the specified bytes

Supervisor with empty coroutine exception handler ignoring all exceptions.

Split source ByteReadChannel into 2 new one. Cancel of one channel in split(input or both outputs) cancels other channels.

Read channel to byte array.

Convert String to CharArray

Does the same as the regular toLowerCase except that locale-specific rules are not applied to ASCII characters so latin characters are converted by the original english rules.

Copy values to a new independent map

Does the same as the regular toUpperCase except that locale-specific rules are not applied to ASCII characters so latin characters are converted by the original english rules.
