#[repr(i32)]
pub enum OutputPrefixType {
    UnknownPrefix,
    Tink,
    Legacy,
    Raw,
    Crunchy,
}
Expand description

Tink produces and accepts ciphertexts or signatures that consist of a prefix and a payload. The payload and its format is determined entirely by the primitive, but the prefix has to be one of the following 4 types:

  • Legacy: prefix is 5 bytes, starts with \x00 and followed by a 4-byte key id that is computed from the key material. In addition to that, signature schemes and MACs will add a \x00 byte to the end of the data being signed / MACed when operating on keys with this OutputPrefixType.
  • Crunchy: prefix is 5 bytes, starts with \x00 and followed by a 4-byte key id that is generated randomly.
  • Tink : prefix is 5 bytes, starts with \x01 and followed by 4-byte key id that is generated randomly.
  • Raw : prefix is 0 byte, i.e., empty.

Implementations§

source§

impl OutputPrefixType

source

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of OutputPrefixType.

source

pub fn from_i32(value: i32) -> Option<OutputPrefixType>

Converts an i32 to a OutputPrefixType, or None if value is not a valid variant.

source§

impl OutputPrefixType

source

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

source

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.
