pub const ENTRY_BYTES: usize = 2400;Expand description
The most a keyring entry holds on every system: Windows’ Credential
Manager keeps 2560 bytes (CRED_MAX_CREDENTIAL_BLOB_SIZE), and a text
kept as a password there takes two bytes a character (UTF-16). A secret
kept as bytes (save_named_bytes) takes its UTF-8 length; this leaves a margin.
