Release Notes

sigstore/fulcio (github.com/sigstore/fulcio)

v1.7.1

Compare Source

v1.7.1 contains a bug fix for extensions for CI providers where the OIDC claims
include HTML escape characters. If a client attempted to verify an extension value,
verification would fail unless an HTML-escaped string was used in the comparison.
Extension values will no longer be escaped.

Bug Fixes:

• Do not HTML-escape extension values (#​2023)

v1.7.0

Compare Source

v1.7.0 includes a change to how proof of possession signatures are verified.
Fulcio has updated the expected hashing algorithm for ECDSA P-384 and P-521
signatures to be SHA-384 and SHA-512, in line with CSR signature verification.
Cosign is actively being updated to support this for when signing with a
managed key and requesting a certificate.

Features

• Allow configurable client signing algorithms (#​1938)
• Use different hash in proof of possession based on key (#​1959)
• Tls verification on OIDC issuers (#​1932)
• feat: adds cert-utility. (#​1870)
• feat: makes leaf optional and other changes. (#​1931)

Bug Fixes

• Remove err impossible condition: nil != nil (#​1934)
• mark principal and issuer class under pkg/identity as deprecated (#​1980)
