okio v2.9.0 Release Notes

  • 2020-10-04

    • Fix: Don't corrupt the Buffer when writing a slice of a segmented ByteString. We had a severe bug where ByteString instances created with snapshot() and readByteString() incorrectly adjusted the buffer's size by their full length, not the length of the slice. This would have caused buffer reads to crash! We do not believe data was silently corrupted.
    • New: CipherSink and CipherSource. Use these with javax.crypto.Cipher to encrypt and decrypt streams of data. This is a low-level encryption API; most applications should use higher-level APIs like TLS when available.
    • New: Promote hash functions md5, sha1(), sha512(), and sha256() to common Kotlin. These are currently only available on ByteString, multiplatform support for HashingSource, HashingSink, and Buffer should come in a follow-up release. We wrote and optimized our own implementations of these hash functions in Kotlin. On JVM and Android platforms Okio still uses the platform's built-in hash functions.
    • New: Support OSGi metadata.
    • Upgrade: [Kotlin 1.4.10][kotlin_1_4_10].
